It does not matter how big you are, there can still be problems.

Naturally I recommend a full website audit, (which is what I do). Today I visited a major international company website where I am registered as a customer, to change a telephone number. Their system would not accept the change because my number had more digits than the form could accept.

It is important that a form is capable of accepting international numbers if you wish to ensure customer satisfaction. Do you stress test your forms?
