How can I make changes to my receipt?

If you completed your purchase after June 19, 2020, please login to My Portal ( and go to Purchase History.  You will be able to add / edit information in the Customer Info fields, and you can then use the Download PDF function to download an updated receipt showing your newly entered Customer Info.   (Please note that accessing Purchase History does require that you have performed email verification on your LF Login account first. It can also take up to 3 hours for the Purchase History page to load for the first receipt, but should load more quickly for subsequent purchases.)    If you completed your purchase prior to June 19, 2020, please contact Customer Support for assistance to making changes to your receipt.

What forms of payment are accepted on your website?

Only credit card payment can be used for payment of exam registration fees. All major credit cards are accepted.

What is needed if I am purchasing for someone else?

If you'd like to make a purchase of a single exam or a single course on behalf of an employee or other individual, please look for the "Gift this course / certification" option located midway down the right margin on the course or exam product page.  (You can search for courses and exams on The gift option is only available for single-course and single-exam purchases. It is not available for bundles (e.g. multi-course bundles, course+exam bundles, etc.).

Where can we add our company’s VAT number when purchasing?

If you need to add your company’s VAT number somewhere on the purchase receipt, please use the Company line in the checkout page to add that info, along with the name of the company. (i.e. You can add something like “Company XYZ, VAT # 123456789” to the Company field when purchasing.)

Where can I get a receipt?

If you made your purchase of a course and/or exam before June 21, 2020, you may find your receipt by logging into and going to the Orders tab. If you purchased after June 21, 2020, please login to and click on Purchase History in the banner at top. If you created a new LF Login account to make the purchase, please be aware that you have to validate the email address on that LF Login account before you can load the Purchase History section. If you have not yet completed that step on your account, logout of the portal and log back in. You should be prompted to validate your email as the first step. Once you have validated your email and then logged back in, go to the Purchase History section. (It may take up to 15 minutes for the page to load, so please click on Purchase History and then check the page again after 15 minutes if needed.)

Why am I getting an error when submitting billing info or why is my credit card being declined?

If you’re running into a payment issue/error, you will need to contact your bank to find out why your card was declined. For example, you might want to check on whether your bank places restrictions on cross-border transactions or on online transactions that exceed a certain amount. If you have a different credit card, we would suggest giving that a try as well. Please also note that debit cards are sometimes known to present issues, so if the issue occurs with a debit card, you may want to try with a credit card instead.

There was an error/issue when I tried to submit payment and the order did not complete. However, I am seeing the transaction listed on my statement?

Blocked transactions may temporarily appear as pending on the customer’s statement before being removed.

When trying to submit payment, I am getting an error indicating my zip code check failed?

You will need to contact your bank to get more information on the payment error you are running into and to double-check the zip or postal code that the bank has on the account matches what you are entering during check-out. We recommend checking that the street address also matches, as sometimes a non-matching street address will lead to the same zip code error.

I double-checked and the zip/postal code and street address matches what the bank has on file, but payment still won’t go through! What can I do?

If you have confirmed that the zip and street address are what your bank have on file for your account, then please try the following:

  1. Clear your cache
  2. Fill out just your email address (and add coupon code if you have one) on the checkout page
  3. Click Proceed with Order
  4. You should be prompted to enter credit card details. Enter the credit card details (but not the billing info side) and click Proceed with Order again.
  5. You should be prompted to enter Billing Info. Enter the billing info along with the zip/postal code that your bank confirmed is correct.
  6. Make sure everything else is completed on the checkout page and click Proceed with Order again.
If above does not help, you will need to try an alternate credit card.

I have a coupon but when I try to use it, I get an error indicating it’s invalid?

Invalid errors typically indicate a coupon is being applied to the wrong product. Please check that you are purchasing the correct product for that coupon. For example, if you have a coupon that is for the LFCS Exam only, you will not be able to use it for the LFS201+LFCS bundle or the LFCE exam, etc. Visit the Promotions FAQ for additional information.
