The 1xBet promo code XPUMP is entered once, in the promo code box of the registration form, before the account is created. You open the sign-up page through the XPUMP registration link, fill in your country, currency and personal details, paste XPUMP into the promo code field, and confirm. After that the code is tied to the account and cannot be added later. The promo code field sits inside the 1xBet sign-up form, on the same screen where you choose your country and currency. It is a single input box, usually labelled as a promo code or bonus code, and it is optional — which is exactly why people skip past it.
