When addressing a No. 10 envelope, where should the address be placed?

When addressing a No. 10 envelope, the address should be placed 10 lines down from the top and 4 inches from the left edge. This placement ensures that the address is well-positioned for automated mailing systems and is easy for postal workers to read. The standard format helps in maintaining consistency and also aligns with postal regulations, which can prevent delays in mail delivery.

The specified distance from the top and the left edge allows for an organized appearance and provides enough space for postal barcodes that may be printed on the envelope, ensuring that the address is not obscured. Proper placement is crucial for effective mail processing, especially since envelopes can be handled by machines that read postal information.

In contrast, positioning the address centered on the envelope may lead to misalignment with postal sorting machines. Placing it at the top-left corner could cause problems, as it is not the conventional location and does not adhere to common addressing standards. Similarly, putting the address in the bottom-right corner could lead to it being overlooked or misread, resulting in delivery issues. The correct approach promotes clarity and efficiency in mail processing.
