This is a great verification mechanism for people ordering from areas with a high credit card fraud rate. Never send credit card numbers by email. This will help prevent honest people from getting their credit card numbers stolen. Mail Tips Small businesses often like the ease of priority US mail envelopes. However, even without the business name on the envelope, vendors are finding that packages are reported to be missing a large proportion of the time.
