Video transcript

The fax number of a company or government office is usually in the letterhead, in the website footer, on the contact page or in your notice. Let me show you what to watch out for when you're looking. The best source is a recent letter: the number is in the letterhead or in the footer. Then there's the footer and the contact page of the website. For government offices, it's often printed right on your notice. Make sure you don't pick up the phone number by mistake. Use a number from a recent letter if you can, because numbers change. And departments often have their own fax numbers. And to be completely honest: mcpfax and Claude don't look up fax numbers on the internet, and they never guess. If you only give a name, Claude asks you for the number. Give the number and have it saved as a contact right away. Next time, the name is all you need. Before sending, you see the recipient, the pages and the price. Once you confirm, the fax is sent. As always, you get the transmission report as a PDF by email. You'll find the link to mcpfax in the description. How to enter the number in the right format is what you'll see in the next video.
