# SES Hospedajes: data send errors

> What to do when SES Hospedajes submissions return an error or a postal code isn't recognised.

## When it shows up

After sending data to SES Hospedajes, you may get notices of:

* **Generic submission errors**: the Ministry reports that some data is invalid (ID format, date, guest ID, etc.).
* **Unrecognised postal code**: the platform returns a specific postal code error, even when the postal code is valid.

## What to do

**Contact support** with:

* **Affected property**
* **Exact error message** SES Hospedajes returned
* **Booking references** or guest IDs involved (if you have them)
* **Screenshot** of the notice, if you have it

We review the submission from our side: in some cases the guest data needs fixing, in others we update the postal code master or adjust the connection.

## Common cases

<AccordionGroup>
  <Accordion title="Badly formatted ID">
    If the ID has non-standard characters or is missing the letter, the send may fail. Check the guest record on the affected reservation. If the data is correct but still fails, contact support.
  </Accordion>

  <Accordion title="Valid postal code but rejected">
    Some new or reassigned postal codes weren't in the initial master list. When you report it, we update the master and the send is accepted again.
  </Accordion>

  <Accordion title="Recurring errors across multiple reservation submissions">
    If errors affect many reservations in a row, there's a deeper issue (configuration, SES connection). Send us the list and we review them in batch.
  </Accordion>
</AccordionGroup>

## When to contact support

**Always.** SES Hospedajes submission errors aren't resolved from the Roomdoo app — they need review on our side.

<Warning>
  Don't upload invented or manually modified data to make the submission pass. The declaration to SES Hospedajes is legally binding, and incorrect data can trigger penalties.
