Does mail go out sooner if it is taken to a main post office?

Yes, mail typically goes out sooner if taken to a main post office. Main post offices often have more resources and higher processing capacities, allowing them to sort and dispatch mail more quickly than local or smaller post office locations. Additionally, main post offices may have more frequent pick-up schedules, ensuring faster transit to the next distribution point. However, actual processing times can vary based on factors like time of day and mail volume.
