CNAE codes for building supply stores

CNAE (Classificação Nacional de Atividades Econômicas) is Brazil's official activity classification. Every company registered with a CNPJ declares one primary CNAE and any number of secondary ones. These are the CNAE 2.3 subclasses most used by building supply stores:

Search primary and secondary CNAE

Many building supply stores register their real activity as a secondary CNAE, because the CNPJ was opened under another primary activity or because they do more than one thing. Neighborhood stores often declare hardware, electrical and plumbing as secondary even if they sell everything. Filtering on the primary code alone misses part of the market.

Who sells to building supply stores

Building supply stores are a sales channel for manufacturers and distributors, and they buy technology and services for their own operations.

How to build a list of building supply stores in Brazil

  1. Pick the codes: start with 4744-0/99 and add 4744-0/01, 4744-0/05, 4742-3/00, 4744-0/03, 4679-6/99 depending on what you sell.
  2. Search them as primary and secondary CNAE.
  3. Keep only active registrations (situação cadastral ativa) to drop unfit, suspended or closed CNPJs.
  4. Narrow by location (state, city, neighborhood) and company size (MEI, ME, EPP, other). To expand distribution, prioritize ME and EPP companies with share capital that fits your minimum order.
  5. Keep companies with contact data (email or phone) and save the filter as a reusable segment.
  6. Write a segment-specific opener and track replies in a pipeline.
