If your payout is stuck behind the Kwai Mercado Pago CURP screen, your CURP is almost certainly fine and the form is what is breaking it. The input field on that screen slips a period into the string while you type, so Kwai receives nineteen characters where it expected eighteen and then tells you the CURP is incomplete or invalid. There is a second blocker sitting underneath that one. The field labelled número de documento is genuinely ambiguous in Mexico, and putting the wrong identifier in it is why some withdrawals leave your balance and reverse days later. The third is name matching, because Kwai checks the name on your profile against the CURP record and Mercado Pago checks its own account holder against both.
Now the advice everyone gives first. Retype it slowly. Make sure you have not read a zero as the letter O, and check the two letter state code. You were expecting me to send you hunting for the typo, right? Do it once, then drop it. The CURP printed on your document is nearly always correct. The problem lives between your keyboard and Kwai’s server.

The extra period is added after you press the key
A CURP is eighteen characters long and it is alphanumeric the whole way through. Letters and digits only. No periods, no spaces, no hyphens and no accents. The first four characters come from your names, the next six are your birth date, then a letter for sex, a two letter state code, three consonants, a homoclave character and a check digit. RENAPO issues it. No valid CURP anywhere contains punctuation.
So when the app insists the CURP is invalid and you can see eighteen correct characters on the document in front of you, something added a nineteenth. Usually it is the keyboard. Gboard and most Android keyboards ship with a shortcut where a double space inserts a period, and typing an eighteen character code with two thumbs produces a double space far more often than you would guess. Autocapitalise makes it worse, because Kwai has not told the field to behave like a code field, so the keyboard treats your CURP as ordinary writing and tidies it up for you. Pasting carries the same trap. Copy the CURP out of a PDF or a WhatsApp message and a trailing period comes along for the ride, and the field will never show you that it is there.
The workaround that actually holds:
- Open a plain notes app and type the CURP there first. Count the characters. Eighteen, no more.
- Turn off the double space shortcut and autocapitalise before you type anything. On Gboard the shortcut sits under Text correction, listed as double space period or double space full stop depending on your language setting.
- Copy from the notes app using select all, so you do not drag a trailing space in with it.
- Paste into the Kwai field, tap to the end of the field and press backspace once. If a character vanishes that you could not see, that was your period.
- Tap somewhere neutral before pressing continue. Some builds trim the field when it loses focus.
- If it still refuses, install a different keyboard app and type the whole thing by hand.
Work out which identifier número de documento is asking for
This is the field that costs people real money, and Kwai documents it nowhere. Look at their own help centre and you will find a Withdrawal section with seventeen articles in it. Every identity article in that section talks about CPF, PIX or a Brazilian bank card. Mexico does not appear once. The form you are staring at is a translated Brazilian one, and número de documento renders número do documento, which in Brazil means the CPF.
Mexico has no single equivalent, which is where the confusion starts. Three different numbers could answer to that label, and they behave nothing alike.
| Identifier | Shape | Issued by | What it identifies |
|---|---|---|---|
| CURP | 18 characters, letters and digits mixed | RENAPO | You as a person |
| RFC for an individual | 13 characters, four letters then six digits then a three character homoclave | SAT | You as a taxpayer |
| CLABE | 18 digits, numbers only | Your bank or wallet provider | The account the money lands in |
The identity field wants the CURP. The CLABE belongs in the account field if the form asks for one at all, and your RFC has no business anywhere on a Kwai withdrawal form. When you cannot tell which field you are looking at, let the input mask answer it. Start typing eighteen mixed characters. If the field stops at thirteen, it wants an RFC. If it refuses letters entirely, it wants a CLABE. If it takes all eighteen, you are in the CURP field.
Now the expensive part. Put the wrong number in and the form will usually accept it, because at that moment nothing is being checked except the shape. The real check happens later, when the transfer is settled against the receiving account. That is why the failure turns up days after a withdrawal that looked like it went through, and why the money comes back to your Kwai balance. Resubmitting the same wrong value reverses the same way.
Your name has to match in every place it appears
Kwai will not tell you this is the problem. It will simply fail. The name attached to your CURP in the RENAPO record is the reference copy, and everything else has to agree with it.
- Your Kwai display name is irrelevant. The legal name field in the withdrawal section is what gets compared.
- Both surnames have to be present. A Mercado Pago account opened with only the paternal surname will not match a CURP that carries both.
- Married names cause this constantly. RENAPO keeps your birth surnames, so a Mercado Pago account under a married name will not clear.
- Accents matter in whichever direction the record holds them. Match the RENAPO spelling rather than the one you prefer.
- An abbreviated or dropped middle name fails exactly like a wrong surname.
The easiest system to change is usually Mercado Pago, since editing your own profile name there is far quicker than correcting a RENAPO record. If the RENAPO record is the thing that is wrong, fix it anyway, because it will block you again on every financial product you ever open.
Mercado Pago is the only rail left, so the account has to be yours
The other withdrawal options were removed. If you are staring at the wallet screen wondering where your old method went, it is gone rather than hidden, and there is nothing to restore. Mercado Pago is a wallet from Mercado Libre. You open an account in their app with a phone number and identity documents, and once it exists it has its own CLABE, which is the eighteen digit number a Kwai transfer actually lands on.
Here is where I stop being funny about this. Do not use a relative’s account or a friend’s account. The name check will fail anyway, so it does not even work. Worse, a wallet taking inbound transfers that do not match its holder is the pattern that gets an account frozen, and the person who lent it to you loses access to their own money while that is reviewed. Open your own. It takes an afternoon.
The same seriousness applies to the CURP itself. Your CURP together with your name and your birth date is enough for a stranger to attempt credit in your name and to open accounts you will never see. There are people in Kwai comment sections and in Telegram groups offering to release stuck withdrawals, and what they ask for is your CURP, a selfie holding your INE and your Kwai login. Nobody legitimate needs any of that. Kwai support runs through the help centre form inside the app and through [email protected], and neither will ever ask you for a password.
The add new withdrawal method button draws before it works
You have probably found the option that sits in the list, looks perfectly tappable and does absolutely nothing. That is not your phone. The wallet screen is shared with markets where several payout methods exist, so the control renders everywhere the app runs. In Mexico there is one method behind it, so the tap has nothing to open. Reinstalling will not change that, and neither will clearing the cache.
What does work is using the slot that is already there. If it is occupied by a half finished attempt from an earlier session, unlink that first and then link again from clean. A stale attempt sitting in an error state will quietly block a good one from saving.
Work through it in this order
- Check your CURP against the printed document once, then stop checking it.
- Turn off the double space period shortcut and autocapitalise.
- Type the CURP into a notes app, confirm eighteen characters, copy it cleanly.
- Paste it into the identity field, tap away from the field, then submit.
- Make the Mercado Pago holder name match the RENAPO record exactly, with both surnames.
- Unlink any failed attempt before you link again.
- If it still fails, write to support with the exact on screen error text and the date of the reversed withdrawal.
Money that has bounced back is sitting in your Kwai balance and it has not gone anywhere. Resist the urge to resubmit five times in one evening. Repeated failures can attract a cooldown, and then you are waiting on a timer as well as a form.
