How to Find Your Florida Business Partner Number (DOR Guide)

Eric DawsonByEric Dawson Business

Your Florida Business Partner Number sits on the back of your Certificate of Registration, on any letter the Department of Revenue has mailed you, and on past state tax returns filed under your account. When none of those documents are on hand, you can find the number by logging into the Florida e-Services portal with your existing e-Services login credentials, or by calling Taxpayer Services at 850-488-6800. The number identifies your business account inside the state’s tax system, and you need it to file returns, renew your certificate, or set up online payments.

What Is a Florida Business Partner Number

A Florida Business Partner Number, often shortened to BPN, is the unique account identifier the Florida Department of Revenue assigns to a business when it registers for state taxes or fees; for a Florida DOR account login to a sales and use tax e-file account, it is used with the Florida Certificate Number. The department uses it to track your account separately from every other business on file, much like a bank uses an account number instead of a name.

Sole proprietors, partnerships, corporations, and nonprofits all receive one once their registration is approved.

The BPN differs from your Federal Employer Identification Number, your Florida Secretary of State document number, and your sales tax certificate number, even though all four sometimes appear on the same piece of mail. Confusing them is a common reason a call to the department takes longer than it should, so knowing which number you actually need saves time before you start searching.

This same identifier applies to every kind of state registration, not only sales tax, since the department defines it as the account number for any business that registers for state taxes or fees. A company that registers only for reemployment tax, for example, still receives a Business Partner Number under this same system.

Why Your Business Partner Number Matters

Your Business Partner Number matters because the Department of Revenue will not process a return, a payment, or a certificate renewal without it. Any business that sells taxable goods or services in Florida must register as a sales and use tax dealer before it opens, and the BPN is the account number attached to that registration. Skipping registration does not remove the requirement; it only means the state has no record tied to your business when a return comes due.

You also need the BPN to enroll in the File and Pay system inside e-Services, which most businesses use after their first return. A preparer, bookkeeper, or accountant handling your filings will ask for this number before setting up electronic access on your behalf. Treat it the same way you would treat a bank account number, since losing track of it does not cancel your tax obligations.

How to Find Your Florida Business Partner Number

Look for your Florida Business Partner Number on paperwork you already have, or retrieve it online or by phone when that paperwork is missing. Five places cover nearly every situation: your certificate, past correspondence, the e-Services portal, a phone call, and email or mail.

On Your Certificate of Registration

The fastest place to look is the back of your Certificate of Registration, Form DR-700014, which the department mailed you after your original registration was approved. Turn the certificate over and the Business Partner Number is printed along with your account details. Keep this certificate displayed at your business location, since state law requires it, and store a copy somewhere safer than the wall in case the original is damaged.

In Past DOR Correspondence

Any letter, notice, sales tax return, or corporate income tax return the department has sent you will carry the same number, usually near the top of the page or in the account summary line. Check a folder of old mail or a scanned copy in your accounting software before assuming the number is lost. Returns filed through a preparer often show it on the confirmation page as well.

In the Florida e-Services Portal

Once you have your e-Services login credentials, you can log into the Florida e-Services portal and view your account details, including the Business Partner Number, from the account summary screen. This route works even if every paper copy of your certificate has been thrown away. New users need to enroll first, and enrollment asks for the same identifiers plus your registered business address.

By Phone

Call Florida Department of Revenue Taxpayer Services at 850-488-6800, or toll free at 800-352-3671, Monday through Friday from 8 a.m. to 5 p.m. Eastern time. Have your Federal Employer Identification Number, certificate number, or Access Source number ready, since the representative uses one of these to pull up your account before reading the Business Partner Number back to you. Calls placed close to opening time tend to move fastest.

By Email or Mail

Email fdortaxpayerservices@floridarevenue.com if your question can wait three to five business days for a reply. For anything that needs a paper trail, write to the Department of Revenue at 5050 West Tennessee Street, Tallahassee, Florida 32399-0100, though mailed requests can take two to four weeks to answer. Phone or the online portal will almost always beat either option for speed.

How to Read the Business Partner Number Format

A Florida Business Partner Number typically runs four to seven digits on paper, but the state’s systems store it as a ten digit field. When a document shows a shorter number, pad it with leading zeros until it reaches ten digits before entering it anywhere online.

Say your certificate shows the number 1234567. To use it in the e-Services portal or on a form that expects ten digits, add three zeros to the front so it reads 0001234567. The same rule applies to a four digit number such as 5678, which becomes 0000005678. Getting this padding wrong is a frequent reason online enrollment gets rejected, so check the digit count before submitting.

Your full state certificate number is a separate, longer figure, 14 digits in total, though only the first 13 are needed to log into the e-file website. Do not mix up the certificate number with the Business Partner Number when filling out a form; they sit next to each other on the certificate but serve different purposes.

Third party filing software such as TaxJar’s AutoFile also asks for this number during Florida enrollment, and it expects the same ten digit, zero padded format described above. Entering the raw seven digit number instead of the padded version is a common setup error when connecting outside software to a Florida account.

How to Get a Business Partner Number for New Registrations

You get a Business Partner Number automatically once the Florida Department of Revenue approves your Florida Business Tax Application, Form DR-1. Registration is free online, and the number arrives with your mailed Certificate of Registration.

  1. Gather your information. Collect your Federal Tax ID (EIN), Social Security Number if you are a sole proprietor, your business structure, owner information, NAICS code, and the date you started doing business in Florida.
  2. Apply through Form DR-1. Register at the Florida Department of Revenue website using the Florida Business Tax Application. Online applications are free; paper applications carry a $5 fee as of September 2026.
  3. Wait for verification. Expect roughly 24 to 48 hours for the department to verify a completed online application.
  4. Receive your certificate. Delivery typically takes 7 to 10 business days by mail to your registered address, and the certificate carries your new Business Partner Number.
  5. Enroll in e-Services. Sign up the same day you receive your BPN, using your FEIN or SSN plus the new Business Partner Number, so you can file and pay online going forward.
Step Timeline Notes
Online registration submitted Immediate Free; paper applications carry a $5 fee
Processing and verification 24 to 48 hours Typical verification window
Certificate received 7 to 10 business days Mailed to your registered address
e-Services access Same day Available once you have received your BPN

What You Need Before You Contact the DOR

Have your Federal Employer Identification Number or Social Security Number, your certificate number, and your business name exactly as registered on hand before you call, email, or log in. Having these ready lets a representative or the portal confirm your identity on the first attempt instead of asking you to call back.

For password retrieval on the e-Services portal, use the Password Retrieval tool on the department’s website rather than creating a new account, since a duplicate account will not show your existing Business Partner Number.

Contact Method Number or Address Hours Response Time
Phone, general tax questions 850-488-6800 or 800-352-3671 Monday to Friday, 8 a.m. to 5 p.m. Eastern Immediate
Email fdortaxpayerservices@floridarevenue.com Not applicable 3 to 5 business days
Mail 5050 West Tennessee Street, Tallahassee, FL 32399-0100 Not applicable 2 to 4 weeks
Phone, refund inquiries 850-617-8585 Monday to Friday, 8 a.m. to 5 p.m. Eastern Immediate

Two other numbers are worth saving even though neither will help locate a Business Partner Number. Collections and delinquent account questions go to 850-617-8600, and the Taxpayer Rights Advocate, who steps in when a case stalls, can be reached at 850-617-8131.

What to Do if You Still Can’t Find Your Business Partner Number

Call Taxpayer Services first if your certificate, mail, and portal login have all failed to turn up the number, since a representative can look up the account directly from your Federal Employer Identification Number alone. Bring your business name, address, and an approximate registration date to speed up the search.

Ask the representative to resend your Certificate of Registration if no copy of it remains. A reissued certificate arrives by mail and shows the Business Partner Number on the back, the same as the original. Regional service centers in Tallahassee, Jacksonville, Tampa, Fort Lauderdale, Miami, and Orlando can sometimes handle a walk in request faster than the phone line during business hours.

Check whether a colleague in accounting or payroll already has the number saved from a past filing when several employees share access to the same account. That single question resolves the search more often than another call to the state.

This guide does not set out the Department’s identity checks or escalation steps for recovering a lost number.

Frequently Asked Questions

What Does a Florida Business Partner Number Look Like?

It appears as four to seven digits on your certificate or correspondence, though the state’s own systems store it as a ten digit field. A seven digit number such as 1234567 becomes 0001234567 once padded with leading zeros. Look for it on the back of your Certificate of Registration or near the account summary on any Department of Revenue letter.

Is There a Fee to Register for a Business Partner Number?

Registering online through Form DR-1 is free. A paper application carries a $5 fee instead. Either method produces the same Business Partner Number once the department approves your registration.

How Long Does It Take to Receive a New Business Partner Number?

Verification usually takes 24 to 48 hours after you submit Form DR-1 online. The mailed Certificate of Registration, which carries the number, typically arrives 7 to 10 business days after approval. Paper applications generally take longer at every step.

Can I Find My Business Partner Number Without Calling the Department?

Yes. Logging into the Florida e-Services portal with your existing e-Services login credentials shows the number on your account summary. Checking the back of your Certificate of Registration or a past tax return works just as well and needs no internet login at all.

Who Do I Contact if My Question Is About a Refund Instead?

Refund questions go to a separate line at 850-617-8585, not the general Taxpayer Services number. Both lines share the same Monday through Friday, 8 a.m. to 5 p.m. Eastern hours. Keep the two numbers separate, since a refund agent will not have your Business Partner Number lookup on hand.

Where Are Florida Department of Revenue Service Centers Located?

Regional service centers operate in Jacksonville, Tampa, Fort Lauderdale, Miami, and Orlando, in addition to the department’s headquarters in Tallahassee. A center can sometimes verify your Business Partner Number in person faster than the phone line during business hours. Call ahead to confirm hours before visiting, since availability varies by location.

Most business owners find their Business Partner Number within a few minutes once they know where to look. Start with the certificate or a recent piece of mail, move to the e-Services portal if those are missing, and treat a call to Taxpayer Services as the last resort.
