NPI registration

The Health Insurance Portability and Accountability Act (HIPAA) requires you to obtain an NPI if you submit claims electronically or if you check claims status or access patient eligibility and benefits information online. If you do not, you may be unable to access patient information electronically from Delta Dental or other health care business associates.

Obtaining your NPI is simple and once obtained, it stays with you for life. To obtain your NPI, simply go to the National Plan and Provider Enumeration System and follow the instructions to complete the application.

When you receive your NPI, please register it with Delta Dental by providing us with a copy of the confirmation containing your NPI that you receive from the National Plan & Provider Enumeration System (NPPES). Send it to your local Delta Dental in one of the following ways:

  • Mail: Delta Dental, Attn: DNAC/ D12, P.O. Box 997330, Sacramento, CA 95899-7330
  • Fax: 916-852-8995
  • E-mail:

  • Fax: 770-641-5395
  • E-mail:

Once you have registered your NPI with Delta Dental, you will have access to Delta Dental's electronic claims status, eligibility and benefits along with other online information. Even if you have not begun to submit claims electronically, you should begin using your NPI on electronic claim status and eligibility and benefits inquiry submissions.
