# Alias rejected by the CNMC

If the CNMC has rejected your alias registration, the rejection reason tells you what to do next. The seven common reasons and how to resolve each one before filing again.

**Language:** en
**Audience:** platform
**TLDR:** Before refiling a rejected alias, check the reason. If the 10-working-day deadline passed or the holder didn't authorise it, just file again and authorise in time. If it's a duplicate request, first check whether the alias is already registered. If the CNMC can't see a link between alias and holder, justify it with your brand, company name or domain. And if the alias is generic, misleading or matches one already registered, you'll need to pick a more distinctive one.

If the CNMC has rejected the registration of one of your aliases, check the
**rejection reason** before starting a new request. The reason tells you whether
it's enough to file again or whether you need to change the alias.

These are the most common reasons and what to do in each case.

## 1. Approval deadline passed

The request was filed on the holder's behalf and was left **pending
authorisation**, but it wasn't approved within the **10 working days** allowed.

This doesn't mean there's anything wrong with the alias.

**What to do:** file a new request and make sure the holder or their
representative authorises it within the deadline. The authorisation steps are in
[Authorising the alias at the CNMC](/platform/en/channels/countries/spain/authorize).

## 2. Holder's decision

The holder received the request and decided **not to authorise it**.

**What to do:** confirm whether the rejection was intentional. If you still want
to use the alias, you'll need to file a new request and authorise it.

## 3. Duplicate request

The CNMC has received more than one request for the same alias and holder.

**What to do:** first check whether the alias already shows as registered or
active. If a valid registration already exists, there's no need to register it
again. If none of the requests went through, start a new one.

## 4. Alias without a link

The CNMC couldn't establish a **legitimate link between the alias and its
holder**.

The link can be justified, for example, by a trademark or trade name, the
company name, an internet domain or any other element proving your right to use
the alias.

**What to do:** review the link you provided, use the one that best justifies the
relationship between the alias and the holder, and file the request again.

## 5. Generic alias

The alias is too generic and doesn't clearly identify a specific company or
organisation.

For example, names based solely on words such as `INFO`, `ALERTA` (alert) or
`OFERTA` (offer) may be rejected.

**What to do:** use a more distinctive alias, clearly related to your brand,
trade name or company.

## 6. Misleading alias

The CNMC considers that the alias could be confused with another company, brand
or organisation.

**What to do:** use an alias that clearly identifies your organisation and can't
be read as belonging to a third party.

## 7. Matching alias

The alias matches another one already registered by a different holder.

**What to do:** use a different alias or, if you believe you have a better right
to it, you'll need to prove that to the CNMC.

## Filing a new request

You can register directly with the CNMC by following the steps in
[Registering your alias directly with the CNMC](/platform/en/channels/countries/spain/self-register).

If you don't have a valid Spanish electronic certificate, someone else can act on
your behalf with an authorisation letter — see
[Registering the alias without an electronic certificate](/platform/en/channels/countries/spain/authorization-letters).

If you have any question about the rejection reason or about refiling your alias,
get in touch and we'll help you.
