I-129f, beneficiary's telephone number

[sfj 0]

Help friends! My boyfriend (American) and I just started to filing for I-129f. When I am filling out "Your Beneficiary's Physical Address Abroad" section, for No.48 Daytime telephone number, I found that my telephone number has 11 digits while the section only allows me to type in 10 digits( American cell-phone format). 

What should I do with that section? should I leave my boyfriend's American number?

You can fill in that section using ink pen i guess  If they are asking for beneficiary’s phone number, then indeed you should put beneficiary’s number there.
