GST Tax Invoice : How many Number of Copies to be made

I am having a wholesale business of Garments :

• For registered dealers we issue Tax invoice in 3 copies. And
• For Unregistered dealer we have got printed 2 copies of tax invoice only. We have not got printed the Transporter Copy as it is of no use for us because normally the Unregistered dealer are Retailers only and we do not send the goods to them through  transporter as Unregistered dealer are local only.

Whether 2 copies are OK or 3 copies is a must even if we keep Transporter Copy spare ?

Rule 48 of CGST Rules 2017

Manner of issuing invoice

48. (1) The invoice shall be prepared in triplicate, in the case of supply of goods, in the following manner, namely,—

(a) the original copy being marked as ORIGINAL FOR RECIPIENT;

(b) the duplicate copy being marked as DUPLICATE FOR TRANSPORTER; and

(c) the triplicate copy being marked as TRIPLICATE FOR SUPPLIER.
