Enrolling in the TDP is easy! You have three convenient enrollment options—online,
by mail or by fax.
Your initial premium payment is required upon enrollment.
Enroll Online
To enroll online, simply complete the TDP Online
Enrollment/Change Form. You can enroll
online using a credit card (Visa® or MasterCard®) for the initial premium payment.
Upon completion of the online enrollment process, a transaction number is provided.
Please retain this transaction number for future reference.
Mail It
Fill out the TDP Enrollment/Change Form and mail it along with your initial premium
payment to United Concordia at the following address:
United Concordia/TDP
P.O. Box 827583
Philadelphia, PA 19182-7583
Fax It
Fax your completed TDP Enrollment/Change Form and initial payment (credit card only)
to 1-888-734-1944.
Avoid Delays in Coverage
To ensure your coverage begins as soon as possible, fill out the enrollment form completely.
An incomplete application may delay your enrollment or result in denial.
In addition, if any information does not match the information contained in the Defense
Enrollment Eligibility Reporting System (DEERS), the enrollment will be rejected and the
initial premium payment will be refunded. You will then have to complete and submit a new
TDP Enrollment/Change Form and initial payment. The enrollment will be processed for the
next available effective date.
Effective Date of Coverage
Upon confirming eligibility through the Defense Enrollment Eligibility Reporting System
(DEERS) and receiving the appropriate initial premium payment and the completed form, United
Concordia will enroll your family members in the TDP. If the TDP Enrollment/Change
Form and the initial payment are received by the 20th of the month, coverage will be processed
for the first day of the following month. If the TDP Enrollment/Change Form and initial premium
payment are received after the 20th of the month, coverage will be processed for the first day
of the second month.
For example: If your enrollment is received by February 20, your coverage will take effect on March 1.
If your enrollment is received on February 21 or through the end of the month of February, your coverage
will take effect on April 1.
Enrollment Confirmation
You will know that your enrollment is confirmed upon receiving your dental identification
card(s). Please do not seek dental treatment without confirmation of enrollment.
If you have not yet received your identification card(s) and are seeking care, contact
United Concordia’s Enrollment and Billing Member Services Department at 1-888-622-2256.
