▁areas ) ▁were ▁created ; ▁in ▁practice ▁this ▁meant ▁that ▁some ▁areas ▁had ▁longer ▁area ▁codes . ▁For ▁example , ▁while ▁En n isk ill en ▁was ▁allocated ▁the ▁area ▁code ▁ 0 3 6 5 ▁( 0 E K 5 ), ▁K esh ▁was ▁allocated ▁ 0 3 6 5 6 ▁and ▁Lis nas ke a ▁ 0 3 6 5 7 . ▁As ▁a ▁result , ▁numbers ▁in ▁En n isk ill en ▁could ▁not ▁begin ▁with ▁ 6 ▁or ▁ 7 , ▁as ▁this ▁would ▁conflict ▁with ▁those ▁of ▁K esh ▁or ▁Lis nas ke a . ▁ ▁All ▁this ▁meant ▁that ▁while ▁En n isk ill en ' s ▁numbers ▁could ▁be ▁six ▁digits ▁long , ▁K esh ' s ▁and ▁Lis nas ke a ' s ▁( and ▁those ▁of ▁other ▁dependent ▁ex changes ) ▁could ▁only ▁be ▁five ▁digits , ▁due ▁to ▁the ▁ 9 - digit ▁limit ▁of ▁the ▁length ▁of ▁a ▁phone ▁number ▁at ▁the ▁time . ▁This ▁sever ely ▁restricted ▁capacity ▁in ▁these ▁areas . ▁As ▁a ▁result , ▁at ▁the ▁Big ▁Number ▁Change , ▁all ▁these ▁dependent ▁ex changes ▁were ▁migr ated ▁to ▁different ▁numbers ▁than ▁their ▁parent ▁ex changes ; ▁in ▁this ▁instance ▁while ▁En n isk ill en ' s ▁ 0 1 3 6 5 ▁( the ▁ 1 ▁coming ▁from ▁Ph ONE day ) ▁was ▁migr ated ▁to ▁ 0 2 8 ▁ 6 6 , ▁K esh ▁went ▁from ▁ 0 1 3 6 5 6 ▁to ▁
