Where to send your Labcorp payment

Labcorp bills arrive with a payment address printed on the statement itself — that is the safest place to send a check or money order. The address changes depending on which Labcorp division billed you and which state you live in, so using the one on your bill ensures the payment reaches the right processing center without delay.

If you have lost the bill or cannot locate the address, call the phone number on your most recent statement or visit the "Pay My Bill" section of Labcorp.com. A representative can confirm the correct mailing address for your account and tell you whether online payment is available for your specific bill type.

Key Takeaways

  • The payment address on your Labcorp bill is the most reliable destination for mailed payments and varies by location and bill type.
  • Online payment through Labcorp.com requires you to enter your account number and date of service, both found on your bill.
  • Mailed checks typically take 7 to 10 business days to post to your account, so send payment early if a due date is approaching.
  • If you set up automatic recurring payments, Labcorp will debit your bank account on the same date each month or billing cycle.

Paying online through Labcorp's website

Go to Labcorp.com and select "Pay My Bill" from the homepage. You will need your account number and the date of service from your bill. Enter both, then choose whether to pay with a debit card, credit card, or bank account transfer.

Online payments typically post within one business day. Labcorp charges no fee for paying by bank account transfer, but credit and debit card payments may carry a processing fee — the website will show you the exact amount before you confirm. If you want to avoid the fee, choose the bank account option instead.

Mailing a check or money order

Write the check or money order to Labcorp and include your account number on the memo line. This single step prevents your payment from being applied to the wrong account. Place the check inside an envelope with the payment address from your bill, add postage, and mail it at least 10 business days before the due date to account for postal delays.

Do not mail cash. If your bill does not show a mailing address or you are unsure which address to use, call the number on your statement first — a few minutes on the phone is faster than a check that arrives at the wrong location and has to be rerouted.

Setting up automatic payments

If you receive regular Labcorp bills — for example, from an ongoing monitoring program or a subscription service — you can set up automatic payments through Labcorp.com. Select "Pay My Bill," then look for an option to set up recurring payments. You will choose the amount, the payment method (bank account or card), and the date each month when the payment should be taken.

Automatic payments reduce the chance of missing a due date, but you remain responsible for checking that the amount charged each month matches your bill. If Labcorp bills you for a different amount one month, the automatic payment will still go through at the amount you set, and you may owe the difference.

What to do if you cannot pay the full amount

Contact Labcorp's billing department directly at the number on your statement. Some accounts are may be able to access for a payment plan that spreads the balance over several months. Labcorp will not automatically set this up — you have to request it, and approval depends on the size of the bill and your account history.

If you are facing financial hardship, explain that when you call. Labcorp may offer options you would not see on the website. Paying something, even a partial amount, shows good faith and often keeps the account from being sent to collections while you work out a plan.

Tracking your payment after you send it

If you paid online, Labcorp will show a confirmation number when ready and send a receipt to your email. Log back into Labcorp.com within a few days to confirm the payment has posted to your account — the status should change from "due" to "paid."

If you mailed a check, wait at least 10 business days before calling to check the status. Have your account number and the check amount ready. A representative can tell you whether the payment has been received and posted. If more than two weeks have passed and the payment has not shown up, ask whether the check was received at all or if it was sent to the wrong location.

Frequently Asked Questions

Can I pay my Labcorp bill over the phone?

Yes. Call the number on your bill and a representative can take payment by debit card, credit card, or bank account. Phone payments typically post within one business day, the same as online payments.

What happens if I miss the due date?

Labcorp may charge a late fee, which will appear on your next bill. If the bill remains unpaid for 60 to 90 days, it may be sent to a collection agency. Paying as soon as you realize you missed the date stops additional fees and keeps the account from escalating.

Is there a fee for paying by credit card?

Yes, Labcorp charges a processing fee for credit card payments, usually 2 to 3 percent of the bill amount. Bank account transfers have no fee. The exact fee appears on the payment screen before you confirm, so you can choose the method that costs less.

Can I pay someone else's Labcorp bill?

You can mail a check or money order to the address on their bill with their account number on the memo line. For online payment, you would need their account number and date of service. Call Labcorp first to confirm they allow third-party payments on that account.

How long does a mailed payment take to show up?

Mailed checks typically take 7 to 10 business days to arrive and post. Mail early if a due date is approaching. Online and phone payments post within one business day, so use those methods if you are close to the important date.
