Small errors on a loan form often matter more than applicants expect. Credifiel reviews every field automatically, so a typo or an inconsistency can shift a decision from instant approval to a slower manual check, sometimes adding hours to what should take minutes.
Most of these mistakes are avoidable with a quick second look before submitting.
Mistakes with personal information
A name spelled differently on the card than on the official ID is one of the most common reasons an application stalls.
Even a missing accent mark or a swapped last name order can trigger this, since the matching process compares the two fields character by character.
Common last names in Mexico with multiple surnames make this comparison especially sensitive to formatting, particularly when one document uses both parental surnames and another only lists one.
Outdated contact details
A phone number no longer linked to the applicant, or an email that bounces, blocks the confirmation step entirely, and the delay usually isn’t visible until the applicant checks their status.
Updating these details before submitting takes less time than fixing them afterward through customer support.
Mistakes with financial details
Both extremes cause problems. A number too low compared to card deposits looks inconsistent, while one too high without proof gets flagged for review, often adding a request for a bank statement.
The safest approach is simply reporting the actual figure that shows up in monthly transactions.
Ignoring existing debts
Leaving out an active loan with another lender doesn’t hide it – Credifiel still sees it through the credit bureau, and the omission itself raises a red flag that a correctly listed debt never would. Loans as small as a few hundred pesos still show up in the same report as larger ones.
| Mistake | Typical consequence |
|---|---|
| Name mismatch | manual identity check |
| Outdated phone or email | confirmation delay |
| Income inconsistency | reduced offer or request for proof |
| Hidden active debt | lower trust score |
Steps to avoid the most common errors:
- Compare the name on the ID with the name on the card exactly, letter by letter.
- Confirm the phone number receives SMS codes before submitting the form.
- Check that the declared income matches recent card deposits closely.
- List every active loan, even small ones from other companies.
- Review the form once fully before hitting submit, not while typing.
- Keep a recent bank statement ready in case it gets requested later.
- Visit https://sin-buro.com/credifiel/ to confirm current requirements before applying.
Additional terms and limitations:
- a joint bank account can complicate income verification, since deposits from two people blend into one statement and make the pattern harder to isolate;
- applying right after a card reissue may add extra checks, since the new card number takes time to sync with the bureau and with Credifiel’s own records;
- multiple same-day applications elsewhere lower trust with Credifiel, even before any of those requests get a decision back;
- a dispute on an old balance keeps that debt marked as unresolved until the dispute itself is formally closed;
- currency other than pesos isn’t always detected automatically, which can understate real monthly income and lead to a smaller offer than deserved;
- a recently changed employer slows down income confirmation until the new job shows up in payroll records or on a fresh bank statement.
