Enrichment of telephone numbers

Telephone number rentals / Enrichment of your database with opt-in partner telephone numbers


Cap Adresse has established a pooled database of 8,000,000 opt-in partner mobile telephone numbers and 26,000,000 opt-in partner landline numbers so that its customers can:

  • Rent a file to conquer a new target
  • Enrich their database with missing land line and /or mobile numbers on existing contacts


Rental: Following the transmission of a brief containing the selection elements, Cap Adresse counts the number of lines that can be mailed or compared with the bloctel file (cold-calling opposition list). Deduplication will also be performed using the customer database as an exclusion file, so that only unique records are used.

Enrichment: First, Cap Adresse conducts an audit to evaluate the ROI for this service.

Based on the surname, first name and postal address, the pooled database and the customer database are then compared to find the missing landline and mobile telephone number(s).
