How your purchase works
When a purchase is made, the payment is handled by one of our payment partners. For your privacy, Mojang does not obtain or store payment information. Instead, when a successful transaction has been completed, we are sent notification of the purchase. Afterwards, you receive an email from Mojang that contains a transaction ID (see below for the different ID types), unless you have typed your email address incorrectly. This transaction ID is your proof of purchase. If you used a gift code or PIN from a prepaid card to start a Minecraft account, we use that code to verify account ownership.
Occasionally, we may need to verify your transaction ID. This could happen if the purchase was interrupted, but the funds were still debited, or if you need to change your email address, but no longer have access to the original email.
If you have lost your transaction ID
After a successful purchase, customers receive an email from Mojang with their transaction ID. Please be sure that your transaction ID was not sent to your email's junk folder. If you do not have that email, you can still recover the ID.
If you paid by Paypal, you can log into your Paypal account and view the ID in your transaction history. Alternatively, you can visit Paypal.com and click "Contact" to request the ID.
If you paid by credit card and your payment was processed through Braintree (which processed certain types of credit card transactions starting December 2013), you'll need to contact Mojang support, providing the name of the cardholder, the date of purchase, email address used, and last four digits only of the card used for the purchase.
If you paid by credit card, and your payment was processed by Skrill/Moneybookers (all payments between 2011 and December 2013, and certain types of credit card transactions after that), you can visit help.skrill.com/pkb_sc_ContactUs to get in touch with a Skrill representative. When contacting them, please be sure to ask for the Merchant Transaction ID.
Types of identifying numbers
Mojang Order UUID - example: 123a456789012b3c4d5e678901f23gh4
This code is generated when a user makes a purchase in the Mojang account system, and is the easiest way for us to track your payment. If you use send us this code, please copy and paste it, as it's very easy to have a typo.
Braintree transaction ID - example: 1a2bcd
This ID is generated when any time you purchase Scrolls or the Shards currency within Scrolls, or certain Minecraft purchases during or after December, 2013. It is a set of six numbers and letters
Paypal transaction ID - example: 1AB23456C7890123D
This transaction ID is generated when you pay with a Paypal account, or make a credit/debit transaction through Paypal as a guest. It is a seventeen character alphanumeric code. If your purchase had to be automatically converted to another type of currency, there may be multiple transaction IDs, so please be sure that you provide the ID from the purchase itself.
Skrill (formerly Moneybookers) transaction ID - example: 9876543210
A Skrill transaction ID is generated when you make a credit/debit card transaction using the respective service. It is a sequence of nine or (after Fall 2013) ten numbers.
Paypal receipt number - example: 1234-5678-9012-3456
While most Paypal users receive a transaction ID, in certain circumstances a customer may have a receipt number, which is four sets of numbers.
Mojang gift code - example: a1b2-c3d4-e5f6 or B2C3-D4F6-G7H8
All Mojang games can have gift codes, which can be identified by three sets of alternating letters and numbers. Gift codes created on an old Minecraft account are in lowercase, while gift codes created on a Mojang account are in caps. If you need to prove account ownership, and you used a gift code that you no longer have access to, you can ask the person who gave you the code to log into www.minecraft.net/profile or account.mojang.com (depending on where the code was purchased) to retrieve this for you. Transaction IDs or order numbers are more helpful than a gift code, as they verify that the original buyer is contacting us.
Prepaid PIN - example: 123 456 7890
This ten digit number comes from prepaid Minecraft cards, available in select retail stores.
DIBS ID - example: 123456789
This is a transaction ID generated by the original Minecraft payment system, and was used for certain transactions until midway through 2011. Like a Moneybookers ID, it is also nine digits. To retrieve this ID, you will need to have saved your original purchase email. If you do not have this, you can contact customer support for alternative account verification methods.
As a transaction ID is considered proof of account ownership, we do not recommend purchasing a used account from another player. Unfortunately, we cannot provide support if you made your purchase through a non-Mojang website or another player.
