How to Set Up a Payment on Your American Express Card

How to make a payment on American Express

You can pay your American Express bill online through their website, by phone, by mail, or through automatic payments. The fastest way is online at americanexpress.com — you log in, go to your account, and send money to American Express directly. By phone, you call the number on the back of your card and a representative walks you through it. Automatic payments (called AutoPay on American Express) let you set a date each month when the payment happens without you having to do anything.

The payment reaches American Express immediately if you pay online or by phone during business hours. Mail takes 7 to 10 business days, so if your due date is soon, mail is not the right choice. American Express charges no fee for any of these methods — the cost is the same whether you pay $50 or $5,000.

Key Takeaways

• Online payments through americanexpress.com arrive the same day and take about five minutes to set up.
• Automatic payments (AutoPay) can be set to pay your full balance, a fixed amount, or your minimum due on a date you choose each month.
• Payments by phone reach American Express the same day; mail takes 7 to 10 business days and should not be used if your due date is within two weeks.
• American Express does not charge a fee for any payment method, but your bank may charge a fee if you use a debit card or bank account that is not linked to American Express.

Paying online through your American Express account

Go to americanexpress.com and sign in with your username and password. If you do not have an online account, you can create one by clicking "Register" and entering your card number, zip code, and date of birth. Once you are signed in, look for "Pay" or "Make a Payment" — the exact wording changes, but it is always near the top of the page.

You will see your current balance and due date. Enter the amount you want to pay. You can pay any amount from $1 up to your full balance. Then choose where the money comes from: a bank account (using routing and account numbers), a debit card, or a credit card. American Express will ask you to confirm the amount and the source before the payment goes through. The payment is sent immediately and shows in your account within minutes.

Keep the confirmation number that appears on your screen. It proves you made the payment and when. If you ever need to show that a payment was sent on time, this number is your proof.

Setting up automatic payments (AutoPay)

AutoPay removes the step of logging in each month. You set it once, and American Express pulls money from your bank account or debit card on the date you choose. To turn it on, sign into americanexpress.com, find "AutoPay" or "Automatic Payments," and choose a payment date between the 1st and the 28th of each month.

You have three choices for what gets paid: your full statement balance, a fixed dollar amount you set, or your minimum payment. Most people choose full balance so they never carry a balance forward. If you choose a fixed amount, make sure it is at least your minimum payment, or you will still be late. You can change or cancel AutoPay anytime, and you can pause it for a single month if you need to.

American Express sends you a reminder email a few days before the payment is due. The money leaves your bank account on the date you set, so plan around your paycheck or other bills that come out around the same time.

Paying by phone

Call the number on the back of your American Express card. A representative will ask for your card number and the amount you want to pay. They will also ask where the money comes from — a bank account or debit card. The payment is processed immediately, and you will receive a confirmation number by phone. Write it down or ask the representative to email it to you.

Phone payments work during American Express's business hours, which are typically 8 a.m. to midnight Eastern time, seven days a week. If you call outside those hours, your payment will be queued and processed the next business day. This method is useful if you have questions about your balance or if you prefer talking to a person, but it takes longer than paying online.

Paying by mail

Write a check or money order and mail it to the address printed on your bill. Include your account number on the check. Mail takes 7 to 10 business days to arrive, so send it at least two weeks before your due date. American Express will not count the payment as on time if it arrives after the due date, even if you mailed it before.

Do not mail cash. If you must pay by mail, use a check, money order, or cashier's check. Keep a copy of what you sent in case there is ever a question about whether it arrived.

What happens after you pay

Your payment shows as pending for a few hours, then moves to posted. Once posted, it reduces your balance immediately. If you paid your full statement balance, your next bill will show a zero balance (unless you made new charges after you paid). If you paid less than your full balance, the remaining amount will appear on your next bill, and you will owe interest on it.

American Express reports your payment to the credit bureaus once a month, usually around the time your new statement closes. Paying on time every month helps your credit score. Paying late (after the due date) hurts it and can trigger a late fee.

Fees and costs

American Express does not charge you a fee to make a payment, no matter which method you use. However, your bank may charge a fee if you pay from a bank account that is not in your name, or if you use a debit card from a different bank. These fees are rare, but they are possible. If you are unsure, ask your bank before you set up the payment.

Some third-party payment services (not American Express) charge a fee to pay your bill. Do not use those services unless you have a specific reason to. Paying directly through americanexpress.com or by phone costs nothing.

Frequently Asked Questions

What time of day does my payment go through?

Online and phone payments go through immediately during business hours. If you pay after midnight Eastern time or on a weekend, the payment is queued and processes the next business day. Mail payments take 7 to 10 business days from the time you drop them in the mailbox.

Can I pay more than I owe?

Yes. If you pay more than your balance, the extra amount becomes a credit on your account. You can use it toward future charges, or you can request a refund. Call the number on the back of your card to request a refund if you overpaid.

What if I miss my due date?

American Express charges a late fee (the amount varies) and reports the late payment to credit bureaus, which can lower your credit score. If you are more than 30 days late, your interest rate may increase. Pay as soon as you realize you missed the date — the sooner you pay, the less damage occurs.

Can I set up AutoPay for a specific charge instead of my whole bill?

No. AutoPay pays your full statement balance, a fixed amount, or your minimum — not individual charges. If you want to pay a specific charge, make a one-time payment online or by phone and enter that amount.

Is it safer to pay online or by phone?

Both are secure if you use americanexpress.com directly or the official number on your card. Never use a phone number or website from an email or text message, even if it looks official. Scammers send fake payment links. Always go to the official American Express website or call the number printed on your card.
