I had now been branded, a small, graceful mark burned into my left thigh, high, under the hip. It had a vertical bar, a rather strict one,
with two curling, frondlike extensions, rather near its base, as though in submission to it. It looked a little like a 'K.' That was mine.
There were variations on this theme. Some of the other girls had similar brands, but, in one respect or another, somewhat different.
There were other sorts of brands, too, but the 'K-type' brand was the most common. Dancer of Gor, Page 66

"I have five brands," said the metal worker, the common
Kajira brand, (the kef), the Dina, the Palm, the mark of Treve, the mark
of Port Kar
. Explorers of Gor,

Tuchuk Brand: Nomads of Gor, page 62

...the brand of the Tuchuk slave, incidentally, is not the same as the generally used in the cities, which, for girls, is the first letter of
the expression Kajira in cursive script, but the sign of the four bosk horns, that of the Tuchuk standard; the brand of the four bosk
horns, set in a manner to somewhat resemble th letter "H", is only about an inch high; the common Gorean brand, on the other hand,
is usually an inch and a half to two inches high; the brand of the four bosk horns, of course, is also used to mark the bosk of the
Tuchuks, but there, of course, it is much larger, forming roughly a six-inch square; following the branding, I supposed that Kamchak
would have one of the tiny nose rings affixed; all Tuchuk females, slaves or free, wear such rings; after these things would on remain,
of course, an engraved Turian collar and the clothing of Elizabeth Caldwell Kajir. Nomads of Gor, page 62

Kassar brand:

The standard of the Kassars is that of a scarlet, three-weighted bola, which  hangs from a lance; the symbolic representation of a
bola, three circles joined at the center by lines, is used to mark their bosk and slaves; both Tenchika and Dina wore that brand.
Nomads of Gor, page 106

Kataii brand: Nomads of Gor, page 106

The standard of the Kataii is a yellow bow, bound across a black lance; their brand is also that of a bow, facing to the left.

Paravaci brand: Nomads of Gor, page 106

The Paravaci brand is a symbolic representation of a bosk head, a semicircle resting on an inverted isosceles triangle.

Northern Brand: It is used mainly up north by the Torvaldslanders, for their bond maids.

The brand used by the Forkbeard, found rather frequently in the north, consisted of a half circle, with, at its right tip, adjoining it, a
steep diagonal line. The half circle is about an inch and a quarter in width, and the diagonal line about an inch and a quarter in height.
The brand is, is like many, symbolic. In the north, the bond-maid is sometimes referred to as a woman whose belly lies beneath the
sword. Marauders of Gor, page 87

Dina brand:

My own brand was the "dina", the dina is a small lovely, multiply pedaled flower, short-stemmed, and blooming in a turf of green
leaves, usually on the slopes of hills, in the northern temperate zones of Gor; it is and exotic, alien flower; it is also spoken of, in the
north, where it grows most frequently, as the slave flower; it was burned into my flesh. Slave Girl of Gor, page 61

There are also other brands on Gor, city brands, penalty brands which are a bit smaller, one thing rarely heard about are personal
brands, but there is mention of them in the books.

I looked at her, puzzled. "Penalty brands," she said. "They are tiny, but clearly visible. There are various such brands. There is one for
lying, and another for stealing." Captive of Gor, page 277

Brand of Treve

"I have never seen a brand of Treve,'"I said.
"It is rare," said Ena, proudly.
"May I see your brand?" I asked. I was curious.
"Of course," said Ena, and she stood up and, extending her left leg, drew her long, lovely white garment to her hip, revealing her limb.
I gasped.
Incised deeply, precisely, in that slim, lovely, now-bared thigh was a startling mark, beautiful, insolent, dramatically marking that
beautiful thigh as that which it now could only be, that of a female slave.
"It is beautiful," I whispered.
Ena pulled away the clasp at the left shoulder of her garment, dropping it to her ankles.
She was incredibly beautiful.
"Can you read?" she asked.
"No," I said.
She regarded the brand. "It is the first letter, in cursive script," she said, "of the name of the city of Treve." Slavegirl of Gor, page 61

Not a Gorean brand as it was something that happened in a dream of a barbarian slave that she recounts to Tarl.

From the box he then took a small, curved knife and a tiny, cylindrical leather flask. I gritted my teeth, but made no sound. With the
small knife he gashed my left thigh, making upon it a small, strange design. He then took a powder, orange in color, from the flask
and rubbed it into the wound. Explorers of Gor, page 330
Incidentally, there are many brands on Gor. Two that almost never occur on Gor, by the way, are those of the moons and collar, and
of the chain and claw. The first of these commonly occurs in certain of the Gorean enclaves on Earth, which serve as headquarters for
agents of the Priest-Kings; the second tends to occur in the lairs of Kurii agents on Earth; the first brand consists of a locked collar
and, ascending diagonally above it, extending to the right, three quarter moons; this brand indicates the girl is subject to Gorean
discipline; the chain-and-claw brand signifies, of course, slavery and subjection with the compass of the Kur yoke."  From Explorers of
Gor, page 12

Left or Right Thigh? Or Somewhere Else?

"Left thigh or right thigh?" he asked. "Left thigh" said Ulafi. Slave girls are commonly branded on the left thigh. Sometimes they are
branded on the right thigh, or lower left abdomen. Explorers of Gor

I also checked certain less common brand sites, such as the lower left abdomen, the interior of the left forearm, and the high instep
area of the left foot. Players of Gor, page 191

Penalty Brands

Three penalty brands are shown here, each start with the first letter of the words liar, thief, traitress,, the last one is the brand of Treve.

"Sometimes, too" she said, "a girl may be branded as punishment, and to warn others against her." I looked at her, puzzled. "Penalty
brands," she said. "They are tiny, but clearly visible. There are various such brands. There is one for lying and another for stealing."
Captive of Gor, page 277

Four men held me, naked, near the brazier. I could feel the heat blazing from the cannister. The sky was very blue, the clouds were
white.
'Please, no!' I wept.
I saw Rask, with a heave glove, draw forth one of the irons from the fire. It reminated in a tiny letter, not more that a quarter of an
inch high. The letter was white hot. 'This is a penalty brand,' he said. 'It marks you as a liar.'
'Please, Master!' I wept.
I no longer have patience with you,' he said. 'Be marked as what you are.'
I screamed uncontrollably as he pressed in the iron, holding it firmly into my leg. Then, after some two to four Ihn, he removed it. I
could not stop screaming with pain. I smelled the odor of burned flesh, my own. I began to whimper. I could not breathe. I gasped for
breath. Still the men held me.
'This penalty brand,' said Rask of Treve, lifting another iron from the brazier, again with a tiny letter at its glowing termination, 'marks
you also as what you are, as a thief.'
'Please, no, Master!' I wept.
I could not move a muscle of my left leg. It might as well have been locked in a vise. It must wait for the iron.
I screamed again, uncontrollably. I had been branded as a thief.
'This third iron,' said Rask of Treve, 'is, too, a penalty iron. I mark you with this not for myself, but for Ute.'
Through raging tears I saw, white hot, the tiny letter.
'It marks you as a traitress,' said Rask of Treve. He looked at me, with fury. 'Be marked as a traitress,' he said. Then he pressed the
third iron into my flesh. As it entered my flesh, biting and searing, I saw Ute watching, her face betraying no emotion. I screamed, and
wept, and screamed.
Still the men did not release me.
Rask of Treve lifted the last iron from the fire. It was much larger, the letter at its termination some one and a half inches high. It,
too, was white hot. I knew the brand. I had seen it on Ena's thigh. It was the mark of Treve. Rask of Treve decided that my flesh
should bear that mark.
'No, Master, please!' I begged him.
'Yes, Worthless Slave,' he said, 'you will wear in your flesh the mark of the city of Treve.'
'Please,' I begged.
'When men ask you,' said he, 'who it was that marked you as a liar and a thief, and traitress, point to this brand, and say, I was
marked by one of Treve, who was displeased with me. Captive of Gor, page 310

Priest-Kings and Kurii Brands

Incidentally, there are many brands on Gor. Two that almost never occur on Gor, by the way, are those of the moons and collar, and
of the chain and claw. The first of these commonly occurs in certain of the Gorean enclaves on Earth, which serve as headquarters for
agents of the Priest-Kings; the second tends to occur in the lairs of Kurii agents on Earth; the first brand consists of a locked collar
and, ascending diagonally above it, extending to the right, three quarter moons; this brand indicates the girl is subject to Gorean
discipline; the chain-and-claw brand signifies, of course, slavery and subjection with the compass of the Kur yoke. Explorers of Gor,

Brands on Gor
"Eta smiled. She pointed to her brand. 'Kan-lara,' she
said."  Slavegirl of Gor Page 80

Symbolism of the Brand:  

The two frond like curls indicate femininity and beauty;
the staff, in its uncompromising severity, indicates that
the femininity is subject to discipline; the upturned
curves on the frond like curls indicate total openness
and vulnerability is usually an inch and a half to two
inches high.   Nomads of Gor,  page 62  

The Kef (The most common of brands)

Her brand, however, was not precisely the same as
mine. It was more slender, more vertical, more like a
stem with floral, cursive loops, about an inch and half
in height, and a half inch in width; it was, I would later
learn, the initial letter in cursive script of the Gorean
expression 'Karjia.' Slave Girl Gor, Page 61
