1. An operator not licensed in the United States requesting an initial Callsign Certificate must provide the following documentation:
•a copy of his or her Amateur Radio operating authorization
•a copy of one other government-issued document that shows his or her name and address (for example, a driver's license or a utility bill) ; sensitive information like a license number or account number can be blacked out
This documentation can either be emailed to the ARRL, or can be presented in person to an in-country ARRL DXCC Card Checker, or can be sent by postal mail to the ARRL.
If you choose the email option, email a copy of your documentation to:
LoTW-help@arrl.org. When the ARRL receives your documentation, it will send you an email message containing your LoTW Account Password, with your Callsign Certificate attached.
If you choose the Card Checker option, contact an in-country Card Checker in advance to ask if they are willing to check your documentation; a list of DXCC Card Checkers is here. The Card Checker will inspect your documents and, if accepted, inform ARRL’s LoTW staff that that your identity and license have been verified. The ARRL will then send you an email message containing your LoTW Account Password, with your Callsign Certificate attached. Do not email your documentation to the Card Checker.
If you choose the postal mail option, place your documentation in an enveloped addressed to
LoTW Administrator
ARRL
225 Main Street
Newington, CT 06111
USA
The envelope must be postmarked from your location. When the ARRL receives your documentation, it will send you an email message containing your LoTW Account Password, with your Callsign Certificate attached. The documentation you submitted will be destroyed after your Callsign Certificate is issued.
刚才去邮件里翻出来看了一下，有三种验证途径，电子邮件， 国外的验证者或者采用邮寄资料的方式。
