Each street is visited, and a number is assigned to all doors and entrances. It is best to use a metric system numbering system, where doorways are assigned a number according to their distance from point zero. Odd numbers are located on the left side of the street, even on the right, rising as they move away from zero. This is compiled on the basis of information gathered during the doorway numbering exercise and will serve as reference for government agencies and utility concessionaires. Implementation Addressing generally falls to the municipality, which will be the contract manager of the operation.
Implementation is split among municipal services, consultants, and companies.
The municipality may set up a unit to manage its involvement. The unit can be an appendage to an urban project and then be gradually integrated into municipal services. The work of codifying, mapping, promoting public awareness, and training will typically be performed by consultants. Conditions for success Sensitizing the population through radio, television, and the press is vital. The effort must be repeated, sometimes for several months.
