## Who regulates A2P SMS in Belgium?

Application-to-person messaging to Belgium is overseen by the Belgian Institute for Postal Services and Telecommunications (BIPT), which licenses the operators that terminate A2P traffic and sets the conditions those routes run under. BroadNet delivers into Belgium over direct operator connections — Proximus, Orange Belgium and Telenet/BASE — rather than through resold or grey routes, so the sender ID, the delivery receipt and the audit trail all come back from the licensed path.

- Telecoms regulator: Belgian Institute for Postal Services and Telecommunications (BIPT).
- Direct operator routes: Proximus, Orange Belgium and Telenet/BASE.
- Sender-ID registration: Alphanumeric sender IDs allowed without formal registration. French + Dutch STOP both honoured.
- Typical lead time: Free-form.

## Sender ID registration in Belgium

Alphanumeric sender IDs allowed without formal registration. French + Dutch STOP both honoured. Registration is not a formality — an unregistered or mismatched sender ID is the most common reason otherwise-valid traffic is filtered, and the failure is usually silent rather than a hard rejection. Plan Free-form for approval and register before you need the route, not during a launch.

- Lead time: Free-form.
- BroadNet files sender IDs on your behalf through the BIPT-licensed operators.
- French + Dutch: Both STOP keywords honoured.
- Time to production: about 5 business days from test access to production.

## Consent and content rules

GDPR + Belgian Telecoms Act. Transactional messages — one-time passcodes, delivery and account alerts — are treated differently from marketing, but the distinction is decided by the content of the message rather than by how the campaign is labelled.

- GDPR + Telecoms Act: GDPR plus Belgian Telecoms Act enforcement.
- French + Dutch: Both STOP keywords honoured.
- Sender ID free: Alphanumeric allowed without formal registration.

## What this means for your integration

Practically, three things decide whether traffic to Belgium performs: a registered sender ID on a BIPT-licensed route, a consent and opt-out record you can evidence, and message content that matches the category it was registered under. BroadNet's compliance engine checks each submission against the Belgium ruleset before it reaches the operator, so a non-compliant send is rejected back to you rather than filtered silently downstream — which is the difference between a fixable error and traffic that quietly disappears.

- Every message returns a delivery receipt (DLR); BroadNet does not publish per-country delivery percentages.
- Indicative list pricing: EUR 0.06 – 0.08 per message.
- Addressable mobile base: 13M subscribers.
- GDPR + Telecoms Act: GDPR plus Belgian Telecoms Act enforcement.

### Do I need to register a sender ID for Belgium?

Yes. Alphanumeric sender IDs allowed without formal registration. French + Dutch STOP both honoured. Allow Free-form for approval. An unregistered sender ID is the most common cause of silently filtered traffic, so register before the campaign rather than during it.

### How long does it take to start sending to Belgium?

Typically 5 business days from test access to production, the short end of our 5–15 business-day onboarding path, because alphanumeric sender IDs need no formal registration here. The technical integration is the same REST or SMPP interface you would use for any other market.

### What does A2P SMS cost in Belgium?

Indicative list pricing is EUR 0.06 – 0.08 per message, with volume tiers below that. The rate depends on the operator, the message category and committed volume — see the Belgium coverage page for the per-operator breakdown.

### What delivery rate should I expect in Belgium?

BroadNet does not publish per-country delivery percentages. Every message on these direct operator routes returns a delivery receipt (DLR), so you can measure delivery on your own traffic, and the platform carries a 99.99% uptime SLA. Grey routes deliver until they do not, and give you no receipt when they fail.
