How to quickly increase your Serasa score.

Increase your Serasa score. It's possible, but it requires consistency over weeks and months. There's no magic formula: the algorithm takes into account payment history, debt level, and relationship with the credit market.

The actions below are those that have the most real and measurable impact on the score. Some produce an effect in weeks, others take a few months to appear in the consultation.

Activate Positive Credit History

The Positive Credit History is the main accelerator of a credit score for those who have no outstanding debts. It records the history of bills paid on time, such as water, electricity, internet, telephone, and financing, and this positive history weighs in favor of the score.

To activate, go to Serasa app or websiteLog in and look for the "Positive Registry" option in your account settings.
Activation is free and the effect starts to appear in 30 to 60 days.
Those who already have an active Positive Credit History and pay their bills on time tend to have a score between 50 and 150 points higher than those who do not.
It is not possible to activate the Positive Credit History if there are active negative entries: first, it is necessary to settle the debts.

Pay bills on the due date.

Recent payment behavior is the most heavily weighted factor in calculating your credit score. Consistently paying bills on time for 3 to 6 months already produces a noticeable improvement in your CPF (Brazilian individual taxpayer registration number) history.

Credit card: pay at least the minimum amount on the due date to avoid late registration. Ideally, pay the full amount to avoid accruing interest.
Utility bills (water, electricity, internet): even short delays can have a negative impact if they result in a negative credit report.
Bills and installments: use automatic debit to eliminate the risk of forgetting the due date.
Active loans: keep your payments up to date, as loans are closely monitored by credit bureaus.

The effect of on-time payments on your credit score is cumulative. Each month without late payments contributes to a positive credit history.

Clear outstanding debts

If there are active negative entries, resolving them is the most important step before taking any other action. With a tarnished credit record, other strategies have limited impact.

Serasa Limpa Nome offers discounts of up to 99% on debts from partners for online negotiation.
After payment, the creditor has up to 5 business days to remove the negative record.
Negotiate the oldest and smallest debts first to clear the largest number of records in the shortest time.
Debts that have expired (more than 5 years past due) are automatically removed from the registry. Check before paying.

Avoid multiple CPF queries.

Every time a company checks a CPF (Brazilian individual taxpayer registration number) for credit analysis, it is recorded in the history. Many inquiries in a short period signal to the algorithm that the consumer is intensely seeking credit, which is interpreted as a risk.

Avoid applying for credit cards from multiple banks at the same time.
Do not apply for unnecessary loans while your credit score is still low.
Compare credit options before applying, so that only the chosen lender checks your CPF (Brazilian tax identification number).

This temporary reduction in consultations usually reverses within 30 to 60 days without new credit requests.

Keep your registration up to date.

Serasa uses registration data to complete a consumer's credit profile. Outdated or inconsistent information can negatively affect the score.

Keep your CPF (Brazilian taxpayer ID) in good standing with the Federal Revenue Service (no outstanding registration issues).
Update your address, phone number, and email address in your Serasa registration to complete your profile.
Link social media accounts and bank accounts to Serasa if the app offers this option, as additional data helps build a positive profile.

How long does it take for the score to go up?

With the above actions implemented simultaneously, the results usually appear like this:

30 days: Activation of the Positive Credit History and updated registration are already being processed.
60 to 90 days: On-time payments + Positive Credit History result in a noticeable increase in score.
3 to 6 months: Those who have cleared their name of bad credit and maintain a good track record can reach the mid-range (501 to 700).
6 to 12 months: A consistent track record can raise the score to the high range (above 700).

Scams promise to raise your credit score in days or weeks in exchange for payment. This doesn't exist. Be suspicious of any paid service that promises quick results on your score.

Frequently asked questions about how to increase your Serasa score.

Is it possible to increase your Serasa score in one week?

No. The score is calculated based on the CPF's (Brazilian taxpayer ID) history over time. The quickest action that can be taken is to activate the Positive Credit History and settle any debts, but the effects take at least 30 days to appear in the score.

Does paying off credit card debt improve your credit score?

Yes, but indirectly and gradually. Keeping your credit card payments up to date and not using more than 30% of your available credit limit are practices that contribute positively to your credit history over the months.

Is there an app to increase your credit score?

No app increases your credit score on its own. The Serasa app is useful for monitoring your score, activating the Positive Credit Registry, checking for negative entries, and negotiating debts. But the increase in your score is a result of the consumer's financial actions, not the app itself.

Is a score of 500 enough to get credit?

It depends on the institution and the type of credit. A score between 501 and 700 is considered good by Serasa and already opens access to basic credit cards and loans from some fintech companies. For mortgage financing or higher credit limits, a score above 700 is more advisable.

Does using your credit card limit hurt your credit score?

Yes, especially if usage is above 30% of the available limit. Keeping the card usage low (below 30%) and paying it in full on the due date are practices that contribute to your credit score over time.

Conclusion

To increase your Serasa scoreThe most effective actions are to activate your Positive Credit History, settle any outstanding debts, and maintain on-time payments for several consecutive months. There are no shortcuts: a history of good payment is built through consistency.
