What Is DENTPIN and How Do You Get One?

Short answer: a DENTPIN is the nine-character ID number the American Dental Association issues to every pre-dental student, and you need it before you can register for the DAT or apply through AADSAS. Getting one is free and takes about ten minutes online through the ADA's DENTPIN portal. It's the first bureaucratic step in this whole process, and by far the least important one, so let's knock it out and get back to actual studying.

What Is DENTPIN, Exactly?

DENTPIN stands for Dental Personal Identifier Number. It's issued by the ADA, and it functions like a permanent student ID that follows you through every ADA-run touchpoint in the process: DAT registration, your AADSAS dental school application, and later steps in the pipeline too.

Once you have a DENTPIN, it doesn't change. You'll type the same nine characters into every ADA form you fill out from now until you're licensed, so get it right the first time and hold onto it.

Nobody explains this clearly when you first start looking into the DAT, which is exactly why "what is DENTPIN" is such a common search. It sounds like it should be complicated. It isn't.

How Do You Get a DENTPIN? Step by Step

Here's the actual process, in order:

1. Go to ada.org and find the DENTPIN portal. Search "DENTPIN" on the site if the direct link has moved, since the ADA reorganizes its pages occasionally.
2. Try the lookup tool first. If you've ever had any prior contact with an ADA testing service, you might already have a DENTPIN on file. Check before requesting a new one.
3. If you don't have one, choose "request a DENTPIN." You'll fill in your full legal name exactly as it appears on your government ID, date of birth, Social Security number (or the alternative process the ADA offers for applicants without an SSN, mainly international students), and a current mailing address and email.
4. Submit the form. The system checks its records to avoid issuing you a duplicate.
5. Receive your DENTPIN. Most students see it on screen immediately and get an email confirmation too.
6. Save it somewhere permanent. A notes app, a password manager, wherever you won't lose it. You'll re-enter this number for DAT registration, test-day check-in, and your AADSAS application later.

That's the whole process. There's no interview, no essay, no waiting on a committee. It's a form.

How Much Does Getting a DENTPIN Cost?

Getting a DENTPIN itself doesn't cost anything. It's a free identifier, not a purchased service.

The confusion here is understandable: right after you get your free DENTPIN, the very next step is registering for the actual DAT, and that step does come with a real exam fee. It's easy to mentally merge the two into one charge when they're completely separate. For the current fee breakdown, see our DAT exam cost guide, and if cost is a genuine barrier, check our DAT fee waiver eligibility guide before you assume you have to pay full price.

How Long Does It Take to Get a DENTPIN?

For the large majority of students, it's instant. You fill out the form, hit submit, and your DENTPIN appears within minutes.

Occasionally the system flags something, usually a name or date-of-birth mismatch against an existing record, and routes you into manual review. If that happens, build in a buffer of a few business days rather than assuming it'll resolve same-day, especially if you're up against a DAT registration deadline.

Exact processing times and portal behavior can shift as the ADA updates its systems, so always confirm current timelines directly at ada.org rather than relying on any single blog post, including this one.

How to Get a DENTPIN: What Reddit Threads Actually Complain About

Search "how to get DENTPIN reddit" and you'll find the same handful of frustrations repeated across threads, not some hidden workaround. Here's what actually comes up, and the fix for each:

• "I forgot my DENTPIN." Use the lookup tool with your identifying information instead of requesting a new one. Creating a second DENTPIN when you already have one on file causes real headaches down the line.
• "The portal keeps erroring out." This is a recurring pattern in forum threads, not a sign you did something wrong. Try a different browser, try again outside peak hours, and if it persists, call the ADA directly instead of resubmitting the same form repeatedly.
• "I'm an international student without an SSN, what do I do?" The ADA has an alternate process for applicants without a Social Security number. Look for that option in the request flow, and give yourself extra lead time since it may involve manual verification.
• "My name doesn't match between my DENTPIN and my ID." Fix this immediately, before test day. Your name at Prometric check-in has to match your identification exactly, and a mismatch traced back to your DENTPIN is a preventable problem if you catch it early.
• "I think I accidentally made two DENTPINs." Contact the ADA to resolve it rather than ignoring it. Duplicate records can complicate DAT registration and your AADSAS application later.

Why This Admin Step Matters Way Less Than You Think

Here's the part that actually deserves your attention: getting a DENTPIN is a ten-minute form, and it has zero bearing on your DAT score. Nobody has ever scored higher because they got their DENTPIN faster or on a nicer-looking portal.

We see the same trap constantly with stressed pre-dents: they treat every piece of logistics, DENTPIN, registration windows, application timelines, as if it's productive DAT prep. It isn't. It's paperwork that needs to get done once so it stops taking up mental space, and that's the entire point of doing it early.

If you're also weighing when to actually sit for the exam relative to your school timeline, our guide to taking the DAT after graduating college covers that decision in more depth. But don't let logistics research masquerade as studying. Get the DENTPIN, register for your date, then put the bulk of your remaining hours into full-length practice tests and reviewing what you actually miss.

Our own scores, top 3 percent on the DAT, came from treating prep as a science: consistent, timed practice under real conditions, and cleaning up every concept behind every miss. That's where your time should go. The DENTPIN is a checkbox, not a milestone.
