Message addressing techniques for a mobile computing device

A computer-implemented method comprising:

• receiving, from an input device, an input sequence of alphabetic or alphanumeric characters as a destination of an outbound message;
• recognizing, by a processor, that the input sequence represents a mnemonic short code based on length of the input sequence and the lack of one or more special characters within the input sequence
• automatically generating, by the processor, a common short code comprising a sequence of numeric digits associated with the mnemonic short code;
• and displaying, on a display, the input sequence comprising the mnemonic short code and the generated common short code in an address field.

A computer-readable storage medium comprising executable computer program instructions that when executed enable a computing system to:

• receive an input sequence of alphabetic or alphanumeric characters as a destination of an outbound message;
• recognize that the input sequence represents a mnemonic short code based on length of the input sequence and the lack of one or more special characters within the input sequence
• automatically generate a common short code comprising a sequence of numeric digits associated with the mnemonic short code;
• and
• display the input sequence comprising the mnemonic short code and the generated common short code in an address field.
