UPS WorldShip requires all e-mail addresses to follow a standard format in order to process the shipment information. An example of a standard e-mail address is johnsmith@ups.com. In this example, "john smith" is the local name, and "ups.com" is the domain name.
All e-mail addresses must follow these standards:
The address must include exactly one @ symbol.
The address must not exceed 50 characters.
The address must include the local name (the text before the @ symbol), the @ symbol and the domain name (the text after the @ symbol).
The domain name must include at least one period (such as ups. com).
The local name can include the letters A through Z (uppercase or lowercase), the numbers 0 through 9, and any of the following characters: ! # $ % & ’r; + - . = ? ^^ _ ` { } ½ ~. The following characters must not be used: < > ( ) [ ] @ , ; : \ / " * or a space.
The domain name must contain two text strings separated by a period, such as ups.com. The name can include the letters A through Z (uppercase or lowercase), the numbers 0 through 9, and the minus sign (-); however, the last character cannot be a minus sign, hyphen, or period.
