Need to talk to a human about your Milestone card? The fastest path to Milestone credit card customer service is one phone number: 1-800-305-0330, answered Monday through Friday from 6:00 a.m. to 6:00 p.m. Pacific Time.
That number, plus a few specialized lines and two mailing addresses, covers everything from lost cards to billing disputes. Here is the full contact list as of July 2026, along with the truth about chat and email support.
Milestone credit card customer service phone number
Call 1-800-305-0330 for general account help: balance questions, payments, fee questions, travel alerts, and account changes. Live agents are available 6:00 a.m. to 6:00 p.m. PT, Monday through Friday, which is 9:00 a.m. to 9:00 p.m. Eastern.
Calling midweek in the early morning usually means shorter hold times. Have your card number or Social Security number ready for identity verification before you dial.
A quick refresher on who you are calling: the Milestone® Mastercard® is an unsecured rebuilding card issued by The Bank of Missouri and serviced by Concora Credit, which is why Concora's name shows up on your statements and mail. If you are checking out the card's support reputation before applying, our full Milestone credit card review covers the fees, limits, and app in detail.

Other Milestone phone numbers you might need
Different problems route to different departments:
- Lost or stolen card: 1-800-304-3096. Call right away. Mastercard Zero Liability protection means you are generally not responsible for unauthorized charges you report promptly.
- Card never arrived: 1-800-314-6340. New cards usually arrive within 14 business days of approval. If yours has not shown up within 21 days, call this Lost/Stolen Department line.
- Fax for documents: 1-503-268-4711.
Does Milestone have live chat or email support?
As of July 2026, Milestone does not list a customer service email address or a live chat option on its official site. Phone and mail are the official ways to reach a person.
Be careful with "Milestone support" email addresses floating around on third-party sites. Sending your card number or SSN to an unverified address is a fraud risk. Stick to the phone lines above or your secure online account.
Manage your account online or in the app
Most routine tasks never need a phone call. Register at mymilestonecard.com to check your balance, view statements, and make payments from a browser.
The Concora Credit app for iOS and Android handles the same jobs: activate your card, track transactions, schedule payments, and set up autopay. If you have more than one Concora-serviced card, a single login covers all of them.
Milestone payment address and mailing address
Two different PO boxes serve two different purposes, so double-check before you mail anything:
- Payments: Concora Credit, PO Box 96541, Charlotte, NC 28296-0541
- General correspondence, including written disputes: Concora Credit, PO Box 4477, Beaverton, OR 97076-4477
Mailed payments can take several days to post. With a 35.9% APR card, a payment that posts late gets expensive, so the app or website is the safer route when the due date is close. You can read more about how that rate works in our credit card APR guide.
What Milestone credit card customer service can help you with
A few requests specifically require the main line:
- Travel alerts. Foreign transactions may be declined unless you call 1-800-305-0330 before using the card outside the U.S.
- Cash advance PINs. You request the PIN by phone and receive it by mail. Our Milestone cash advance guide explains the costs before you commit.
- Billing disputes. Start by phone or in writing to the Beaverton address. Knowing what happens when you dispute a charge helps you set expectations on timing.
- Fee and due date questions, plus hardship options if you are behind.
Frustrated with the fees? You have options
Many customer service calls about this card are really fee complaints: the $175 first-year annual fee, then $49 a year plus $12.50 a month from year two. No phone call makes those go away, and there is no credit limit increase program to grow into.
If that is your situation, it may be worth comparing before renewal. The Aspire® Cash Back Rewards Mastercard is a similar unsecured card with no security deposit, prequalification for up to a $1,000 limit, reporting to all three bureaus, and up to 3% cash back. Our Aspire Mastercard review breaks down the full costs side by side.
