Who This Page Is For

Dental providers and Delta Dental members looking for claim-submission routes, plus providers registering their NPI with Delta Dental of Pennsylvania. Because Delta Dental is a federation of independent state companies, the right number depends entirely on which one covers you, check your ID card before faxing anything.

What is Delta Dental's fax number?

Delta Dental isn't one company, it's a federation of 39 independent state member companies, each licensed and operated separately. The national deltadentalins.com page lists mailing addresses by state and encourages electronic claim submission, but publishes no single fax number, because there isn't one. Each state affiliate maintains its own. Confirmed examples: Delta Dental of Virginia faxes to 540-491-9717, Delta Dental of Pennsylvania uses its NPI registration / Provider Onboarding fax (not a claims fax) at 717-774-1770, and Delta Dental of Kentucky to 877-664-3607.

Which route should I use?

Check your Delta Dental ID card or plan documents for the exact state member company name, for example "Delta Dental of Virginia" rather than just "Delta Dental."
Go to that specific affiliate's own website, not the national deltadentalins.com page, to find its fax number.
If your state affiliate doesn't publish a fax number at all, use its electronic submission portal instead.

Documents to include

For Pennsylvania NPI registration, send a copy of your NPPES NPI confirmation. For dental claims, use the standard ADA Dental Claim Form, most affiliates accept the same form regardless of state, but confirm on your specific affiliate's site since requirements can vary slightly.

Several other health and life insurers follow a similar pattern. Our directory also covers Voya's fax numbers, how to fax Anthem, the Humana fax page, BCBS Texas's claims fax, sending a fax to EyeMed, and GEHA's fax number, each with its own destination and audience notes.

Whichever state affiliate covers you, Fax.Plus's Free plan handles a single dental claim for $0.20 a page after the first 10, no subscription.

FAQs

Why doesn't Delta Dental have one national fax number?

Delta Dental operates as 39 independent state member companies rather than a single national insurer, so each state affiliate publishes and maintains its own fax number.

How do I find my specific Delta Dental affiliate's fax number?

Check your ID card or plan documents for your state member company's name, for example Delta Dental of Virginia, then look up that specific affiliate's claims page rather than searching for a generic Delta Dental number.
