I don’t have enough information to determine exactly what you’re asking about with just “lada 2 de dónde es.” If you’re referring to the LADA dialing code system used in Mexico, the first digit of a LADA code indicates a broad region, and the combined digits specify the state and locality. For example, the LADA 2 region generally covers the eastern area of Mexico, including states like Veracruz and parts of Puebla, but exact locality mappings depend on the full 3-digit code (LADA) and the local city or town. To give you a precise answer, please clarify:

• Are you asking about a specific LADA code (e.g., 22X, 22Y, etc.) and which locality it corresponds to?
• Do you want a general explanation of how LADA codes map to states and municipalities, or a list of exact localities for a particular 3-digit LADA?

If you can share the full LADA code or the specific city you have in mind, I can identify where that LADA code originates and which locality(s) use it.
