The head-office address for Ambetter Insurance, in Missouri. ZIP code 63105.

How to address the envelope

  1. Write the address as printed

    The front of the envelope carries 7700 Centene Plaza Forsyth Blvd, Clayton, MO 63105 and nothing else in the address block. Check the 63105 digit by digit before it goes in the post.

  2. Add the return address

    Print your return address in the top-left corner. Without it, an undeliverable letter is simply lost instead of returned to you.

  3. Send it by certified mail

    Certified, not courier: buy it at the counter, keep the postmarked slip, and the letter to Clayton is traceable from the article number until it is signed for.

  4. Keep the proof together

    The postmarked receipt, the tracking record and your signed copy of the letter are the set that proves the request; with You choose the end date (today or a future date); do not end it before new coverage starts, the set is what the dates are read from.

The letter to send

The request itself is short: Ambetter Insurance is asked to end the account, stop the charges and confirm in writing, with the policy number, the name on the policy and the date you want cover to end where the brackets are.
