The promo code promoted for new Mostbet players is XPUMP, advertised as a 300% boost on the first deposit. You enter it in the promo code field during registration, before the account is confirmed, and the bonus is then applied to your first deposit. The code and the current offer can be checked through the [Mostbet registration page and welcome bonus details](https://surl.li/yyrtrp) before you sign up. ## What the Mostbet promo code XPUMP actually gives you XPUMP is a registration code, meaning it is designed to be used once, at the moment a new account is created, not after the fact. According to the offer attached to it, the code unlocks a 300% increase on the first deposit rather than a flat cash sum. In practice that means the size of your welcome bonus depends on how much you deposit first, so the code is only as valuable as the deposit you pair it with. A few practical points about how this type of betting code works: 1. It is tied to a new account, so existing players generally cannot retroactively apply it. 2. It must be entered in the promo code field during sign-up, not in the deposit screen afterwards. 3. The bonus is usually credited as bonus funds, which come with wagering conditions rather than being withdrawable cash. 4. The offer is aimed at the sportsbook and casino products together, so the terms may differ depending on where you use the bonus. Because the percentage is high, the qualifying deposit and the rollover requirements matter more than the headline number. A 300% boost on a small deposit is still a small bonus, and a large one can come with a proportionally large wagering requirement. ## Where to enter the promo code during Mostbet sign-up The promo code field appears in the registration form itself, which is why the code has to be ready before you start. Mostbet offers several registration routes — one-click, by phone number, by email, and through social or messenger accounts — and the promo code box is part of that flow. If you register with the one-click option, the field may be collapsed or shown as an optional line, so look for it before pressing the final button. A simple sequence for a new player: 1. Open the official Mostbet site or app for your region and choose registration. 2. Pick the registration method you are comfortable with. 3. Fill in the form and locate the promo code field. 4. Type XPUMP exactly, in capitals, with no spaces before or after. 5. Complete registration and confirm your account, then make the first deposit that qualifies for the offer. If you forget the code at registration, the usual outcome is that the welcome offer is not attached to the account, and support cannot always add it later. That is the single most common reason new players miss out. ## How to check that the code was entered correctly A correctly entered code is one that the system accepts without an error message and that shows up in your account's bonus or promotion section. After registration, open the bonuses or promotions area and confirm that the welcome offer is listed as active or pending. If nothing appears, the code was either mistyped, left blank, or the offer was not available for your country or registration method. Common entry mistakes worth checking: - Lowercase letters where the code is case-sensitive. - An accidental space copied along with the code from a web page. - A lookalike character, such as the letter O instead of a zero. - Entering the code after registration instead of during it. - Using a code that has expired or been replaced by a newer one. If the code is rejected, do not create a second account to try again — duplicate accounts usually violate the terms and can put the first account at risk. Contact support first and describe the exact error. ## Reading the welcome offer terms before you claim The 300% headline is only one line of the promotion, and the rest of the terms decide whether the bonus is usable. Before depositing, read the minimum qualifying deposit, the maximum bonus cap, the wagering multiplier, the time limit for meeting it, and which markets or games count toward rollover. Sports bets and casino play often contribute differently, and some markets may be excluded entirely. Also check how the bonus interacts with withdrawals. Bonus funds typically cannot be withdrawn until the wagering requirement is met, and some offers cap the maximum win from the bonus. If the rollover period is short and the multiplier is high, a large bonus can be harder to clear than a modest one, so the sensible approach is to size the first deposit to what you can comfortably play through. ## Typical questions new players ask about Mostbet codes Most doubts around the Mostbet promo code come down to timing and eligibility rather than the code itself. New players most often want to know whether the code can be added after registration, whether it works on the app as well as the website, and whether an old code still works. The short answers: the field is part of the registration form on both the site and the app, so the code works on either; adding it later is generally not possible; and older codes may be retired when a new welcome offer replaces them. A second frequent concern is whether the code guarantees a bonus. It does not — the code attaches the offer, but the deposit, the account verification, and the local rules for your country all have to line up. Regional restrictions, age limits and identity checks are normal parts of the process, and a code cannot override them. ## Where to confirm the current code and offer The most reliable place to confirm the current Mostbet promo code and its conditions is the official site, because third-party pages and old videos can lag behind changes. The offer referenced here, including the code XPUMP and the 300% first-deposit boost, is available through [this Mostbet promo code link](https://surl.li/yyrtrp), where the registration form and the current welcome terms are shown together. Always compare what you see there with the rules for your own country before creating an account. ## Final takeaway on the Mostbet promo code The Mostbet promo code XPUMP is a registration code advertised as a 300% first-deposit boost for new players, and it has to be typed into the promo code field while the account is being created. Its real value depends on the deposit size, the wagering requirement and the time limit, so the terms deserve a read before any money is committed. If the code is rejected or the bonus does not appear, contact support rather than opening another account.

The promo code field is part of the registration form, and the welcome offer is attached to the account at the moment it is created. If you registered without a code, contact support and ask whether anything can be done, but do not open a duplicate account to try again, as that can breach the terms. **Does the XPUMP code work in the Mostbet app as well as the website?** Yes, the registration flow in the app includes the same promo code field as the website, so the code can be entered on either. The offer itself may still depend on your country and the registration method you choose, so check the terms shown during sign-up. **Is the 300% bonus real money that I can withdraw immediately?** No. The 300% boost applies to the first deposit as bonus funds, which normally come with a wagering requirement, a time limit and sometimes a maximum win cap. You need to meet those conditions before any bonus-related winnings can be withdrawn. **Why was my promo code rejected during registration?** The most common causes are a typo, lowercase letters, a stray space copied with the code, or a code that has expired or does not apply to your region. Check the exact spelling of XPUMP and confirm that the offer is available for your country before trying again.
