American Express offers three main ways to pay your bill: online through your account, by phone, or by mail

The fastest and most common method is paying online through your American Express account. You log in, select the payment amount, choose the date it should process, and confirm. The payment typically posts within one business day. You can pay the full statement balance, the minimum payment, or any amount in between.

If you prefer not to use the website, you can call American Express directly at the phone number on the back of your card. A representative will walk you through the payment over the phone and can process it when ready. This method works if you do not have internet access or prefer speaking with someone.

Mailing a check is the slowest option. You write a check, include your account number, and mail it to the address listed on your statement. Mail typically takes five to seven business days to arrive, so plan ahead if your payment due date is approaching.

Key Takeaways

  • Online payment through your American Express account is the fastest method and usually posts within one business day.
  • You can pay by phone by calling the number on your card, and the payment processes when ready when you confirm.
  • Mailing a check takes five to seven business days, so send it well before your due date to avoid late fees.
  • You can pay your full balance, minimum payment, or any amount between the two on any payment method.
  • Late payments trigger a fee and may increase your interest rate, so confirm your payment posts before the due date passes.

Paying online through your American Express account

Log into your American Express account on the website or mobile app. Select "Pay" or "Make a Payment" from the menu. The system will show your current balance, minimum payment due, and the due date. Enter the amount you want to pay and select the date you want it to process.

American Express accepts payment from a bank account (checking or savings) or from another American Express card. If you use a bank account, provide your routing number and account number, or select a previously saved account. The payment will post within one business day in most cases.

You can schedule payments in advance through the online portal. This is useful if you want to set up a recurring payment on the same date each month or if you want to may support a payment posts by a specific date. You can also change or cancel a scheduled payment before it processes.

Paying by phone

Call the customer service number on the back of your American Express card. A representative will ask for your account number and the amount you want to pay. They will confirm the payment date and the source account (bank account or another card).

Phone payments process when ready when you confirm them with the representative. This means the payment is submitted right away, though it may take one business day to post to your account. Phone payments are useful if you are close to your due date and want to may support the payment is submitted the same day.

American Express does not charge a fee for paying by phone. The call is free, and there is no additional cost beyond the payment amount itself.

Mailing a check

Write a check for the amount you want to pay. On the memo line, write your American Express account number so the payment is credited to the correct account. Include the check and a payment stub (if your statement came with one) in an envelope.

Mail the check to the address listed on your statement under "Payment Address" or "Make Checks Payable To." Do not mail it to the general customer service address. The payment address is usually a lockbox operated by a bank, not an American Express office.

Mail typically takes five to seven business days to arrive. If your due date is fewer than seven days away, mailing a check is risky because it may not arrive in time. If you are cutting it close, use online or phone payment instead.

What happens if you miss your due date

If your payment does not post by the due date shown on your statement, American Express will charge a late fee. The fee amount depends on your account history and the size of your balance. A first late payment typically costs $25 to $35. Subsequent late payments in the same billing year may cost more.

A late payment also triggers an increase in your interest rate. American Express may raise your APR (annual percentage rate) on new purchases and on any existing balance. The rate increase can last for six months or longer, depending on your account terms.

Late payments are reported to credit bureaus and appear on your credit report for seven years. Even one late payment can lower your credit score and make it harder to borrow money in the future. If you are struggling to pay, contact American Express before the due date to discuss options.

Setting up automatic payments

You can set up automatic payments through your American Express account so that a payment is deducted from your bank account on the same date each month. Log into your account, go to the payment settings, and select "Automatic Payments" or "Recurring Payments."

Choose whether you want to pay the full statement balance, the minimum payment, or a fixed amount each month. American Express will deduct that amount from your bank account on the date you select. You can change or stop automatic payments at any time through your account settings.

Automatic payments reduce the risk of missing a due date because the payment is submitted without you having to remember. However, you should still monitor your account to make sure the payment posts correctly and that your bank account has enough funds.

Paying from outside the United States

If you are traveling or living outside the United States, you can still pay your American Express bill online or by phone using the same methods described above. Online payment and phone payment both work internationally as long as you have internet access or can reach a phone line.

Mailing a check from outside the United States is slower and riskier because international mail can take several weeks. If you are abroad and need to pay quickly, use online or phone payment instead.

Some countries have local American Express payment centers or partner banks where you can pay in person. Contact American Express customer service to ask whether your country has a local payment option.

Frequently Asked Questions

How long does it take for an online payment to post?

Online payments typically post within one business day. In some cases, a payment may post the same day if you submit it early in the morning. Check your account the next business day to confirm the payment has posted.

Can I pay my American Express bill with a different credit card?

You can pay with another American Express card through the online portal or by phone. You cannot pay with a Visa, Mastercard, or Discover card. Paying a credit card bill with another credit card also triggers a cash advance fee, which is usually higher than a regular purchase fee.

What if I pay more than my statement balance?

If you pay more than you owe, the extra amount becomes a credit on your account. American Express will explore the credit to your next statement. You can also request a refund of the credit balance, though this may take several business days to process.

Is there a fee for paying my bill online?

No. American Express does not charge a fee for paying online, by phone, or by mail. The only cost is the payment amount itself. Some banks may charge a fee if you use their bill pay service to send a check to American Express, so check with your bank.

What should I do if my payment was not received?

Log into your account and check the payment history to see whether the payment posted. If you paid online or by phone, it should appear within one business day. If you mailed a check and it has been more than seven business days, contact American Express customer service with the check number and amount to investigate.
