Category policy

PoSTBox vets every advertiser before they can publish (see advertising on PoSTBox). Some categories are never allowed, regardless of how the applicant otherwise checks out.

Never allowed

• Tobacco manufacturing (NACE 12)
• Gambling and betting (NACE 92)
• Tobacco wholesale/retail (NACE 46.35 / 47.26)

Restricted

These aren't identifiable from a registry code alone, so they're enforced through review rather than automatic rejection:

• Adult content
• Unproven or misleading health/supplement claims
• Vaping paraphernalia
