First of all thank you for reading this message.
I am in a peculiar condition. I bought around 25 domains from a reseller of domains (early 2000). Soon I realised that I am having less services and that I should transfer my domains to a (new) registrar. Since then I started transferring my domains to a registrar. The reseller was providing security codes till then (and is ready till now) but the security codes provided by the reseller are being discarded by the registrar say INVALID CODES! When I contacted the reseller, they straight away reply that they provided me with the codes provided to them by ICANN, and the Registrar takes no responsibility of it.
Advices are appreciated.
Thanks again.
Check to ensure the names are unlocked prior to attempting to transfer.
Check to see if the first letter of the code is a capital letter - if so, try using a lower case letter instead - some software programs such as Word or email clients such as Outlook may have capitalized the first letter without it being intended. Also check to make sure there is no space being entered at the end if copy/pasting the code.
Good luck.
