1 February passed: what the TSE teaches about clean data

Election day 1 February 2026 is behind us. The TSE will publish the final count on its timeline; companies do not need that declaration to tidy their own house. The exportable lesson is not political: a register with rules, one source, and a process that does not switch off because “today there is a queue.”

If 30 January you typed 200 sign-ups by hand, 11 February is the day to measure duplicates, invented IDs, and names that do not match. The TSE API is for the rest of the four-year term, not for election week. Software born without that validation can be fixed; more expensive, but possible.

A February cleanup that actually ends

• List records without a valid ID or with an impossible format.
• Merge duplicates with a rule (collections lead, not whoever has more empty fields).
• Leave validation on. Turning it off “for now” is returning to January.

March will bring the official presidential declaration. Your database does not need a bulletin to stop accepting junk.

The TSE is not a fashionable vendor. It is the reminder that master data has an owner.

Quote the integration if February already showed the mess. It is cheaper than charging the wrong person in April.
