Beware of impersonators

It has come to our attention that the names of GlaxoSmithKline, GSK and our group companies are being used in connection with bogus transactions, advertisements and emails using our corporate identity to solicit payments into bank accounts that do not belong to us. They tend to use actual GSK corporate identity / tax registration numbers, which are available in public domain, to make the advertisement or email look more authentic. Please be advised that such advertisements and emails are not connected with the GlaxoSmithKline group in any way.

GlaxoSmithKline group would like to caution the public to verify the identity of individuals / entities purporting to be / claiming to have association with any GlaxoSmithKline (GSK) group company before making any dealings and payments with them.

GSK is not in the business of sale of bulk drugs. The GSK India product portfolio includes finished pharmaceutical / healthcare products. GSK also does not charge any fee (refundable or otherwise) for job applications or in its recruitment process.

If you come across any such persons claiming to be associated with GSK, but using email addresses not ending in, or otherwise appearing suspicious, please inform us by sending an email to, so that we can confirm to you on the genuineness of the matter.
