# NumeroVero.Online

> NumeroVero.Online is a B2B SaaS platform for validating, cleaning and classifying mobile phone number databases before messaging, CRM and marketing operations.
>
> It can validate whether a mobile number is technically valid and usable and can check whether a number is currently associated with supported messaging channels including WhatsApp, RCS, Viber, Telegram and iMessage.
>
> Results describe technical status detected at the time of the check. They do not constitute marketing consent, do not identify the owner of a number and do not guarantee message delivery, reading or response.

NumeroVero.Online is operated by akdigital, Via Giacomo Puccini 1, 46025 Poggio Rusco (MN), Italy. VAT / Tax ID: 02778530200.

The platform is designed primarily for businesses that already possess phone-number databases legitimately, such as customers, leads, CRM records or other business contact datasets.

NumeroVero.Online does not provide contact lists and its channel checks are not intended to generate new contact databases.

Typical use cases include:

- cleaning CRM phone-number data;
- removing unusable or malformed phone numbers;
- detecting duplicates;
- validating mobile numbers before campaigns;
- measuring how many contacts are technically reachable on a specific messaging channel;
- segmenting audiences by communication channel;
- reducing campaign attempts toward unusable numbers;
- selecting alternative messaging channels;
- exporting cleaned results back into a CRM;
- performing bulk validation through the API.

## How to choose the correct service

- [Number validation](https://numerovero.online/en/number-validation.md): Use when the question is whether a mobile phone number itself is technically valid and usable. This is the recommended first step for old, imported or unverified CRM databases.
- [WhatsApp check](https://numerovero.online/en/whatsapp-check.md): Use when the question is whether a phone number currently has an active WhatsApp account.
- [RCS check](https://numerovero.online/en/rcs-check.md): Use when the question is whether a phone number currently appears reachable through RCS.
- [Viber check](https://numerovero.online/en/viber-check.md): Use when the question is whether a phone number currently appears associated with Viber.
- [Telegram check](https://numerovero.online/en/telegram-check.md): Use when the question concerns technical presence or reachability on Telegram.
- [iMessage check](https://numerovero.online/en/imessage-check.md): Use when the question concerns technical presence or reachability through iMessage.

Number validation and channel checks are different operations.

A technically valid mobile number is not necessarily present on WhatsApp, RCS, Viber, Telegram or iMessage.

Likewise, detection of a messaging account does not constitute authorization to send marketing communications.

For campaign preparation, the usual workflow is:

1. import or paste the phone-number list;
2. normalize and validate the numbers;
3. identify invalid rows and duplicates;
4. optionally check the desired messaging channel;
5. segment the resulting audience;
6. export the result as CSV;
7. import the cleaned or segmented data back into the CRM or campaign platform.
